Short answer
By testing them, the way a judge tests the stories of suspects. Many different answers do not mean there is no right answer. They mean most of the answers are wrong. And the religions say opposite things, so they cannot all be right. A message from God (﷾) would pass five tests. It would say it comes from Him. It would not contradict itself or the facts. It would be kept as it was given. It would bring a proof no one can match. And everyone could reach it. Many holy books never say that God (﷾) sent them. The rest contradict themselves or were changed. Only the Qur'an meets all five, and it asks to be tested: it dares anyone in doubt to make one surah like it (2:23).

Full explanation
Step 1: Many answers do not mean no answer
Ask a class to add up a long sum, and you may get ten different answers. That does not mean the sum has no answer. It means most of the class got it wrong. A judge with ten suspects thinks the same way. He does not decide that there was no crime. He checks each story against the facts until one stands. Religions can be checked in the same way. The Qur'an itself asks for this. To those who said only their own people would enter Paradise, it answers: "Produce your proof if ye are truthful." It also says that truth stands out clear from error. A book that asks others for their proof must bring its own.
“And they say: "None shall enter Paradise unless he be a Jew or a Christian." Those are their (vain) desires. Say: "Produce your proof if ye are truthful."”
“Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in Allah hath grasped the most trustworthy hand-hold, that never breaks. And Allah heareth and knoweth all things.”

Step 2: Five tests for a message from God (﷾)
So how can we tell a message from God (﷾) from a book that people wrote? Anyone, believer or not, can agree on five tests. First, the book would say plainly that God (﷾) sent it. If it never says so, there is no reason to treat it as His word. Second, it would not contradict itself, or the world He made, because He makes no mistakes. Third, it would be kept as it was given. If people changed it, no one could tell His words from theirs. Fourth, it would bring a proof that no human being can match. Fifth, everyone could reach it. A God who will judge people by His message would not hide it from them. Tests one to three can only rule a book out. Only the fourth can show that a book is from God (﷾).
“Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.”
“We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).”
“And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true.”
“Who receiveth guidance, receiveth it for his own benefit: who goeth astray doth so to his own loss: No bearer of burdens can bear the burden of another: nor would We visit with Our Wrath until We had sent a messenger (to give warning).”
Take any book said to be from God (﷾), and ask five questions in turn.
Test 1
Does it say that it comes from God (﷾)?
No Then it is not a message from God (﷾), however wise it is. Set it aside.
Test 2
Is it free of contradiction, with itself and with the world God (﷾) made?
No God (﷾) makes no mistakes. Set it aside.
Test 3
Was it kept as it was given?
No No one can tell God's (﷾) words from people's. Set it aside.
Test 4
Does it bring a proof that no human being can match?
No Then nothing shows it is from God (﷾). A careful writer could pass tests 1 to 3.
Test 5
Is it within reach of everyone it will judge?
A book that passes all five is God's (﷾) message, and should be followed. The Qur'an claims all five, and asks to be tested.
Step 3: They cannot all be true
Some say every religion is a path to the same truth. They tell the story of blind men who each touch one part of an elephant. But the story only works because someone can see the whole elephant, and knows that the blind men are wrong. The one who tells it claims to see what he says no one can see. And the religions do not just see different parts. They say opposite things. The Gospels say Jesus "yielded up the ghost" on the cross. The Qur'an says "they killed him not, nor crucified him". The Bible says it is "appointed unto men once to die, but after this the judgment". Other faiths teach that the soul is born again and again. Opposite answers cannot both be true. So the religions cannot all be right, and we still have to ask which one is.
“Jesus, when he had cried again with a loud voice, yielded up the ghost.”
“That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not:-”
“And as it is appointed unto men once to die, but after this the judgment:”
| The question | One answer | The opposite answer |
|---|---|---|
| Did Jesus die on the cross? | The Gospels: yes, he gave up his spirit there. | The Qur'an: no, he was neither killed nor crucified. |
| How many times does a person die? | The Bible: once, and then comes the judgment. | The faiths of rebirth: the soul is born again and again. |
| Is there a God who acts in the world? | The Torah and the Qur'an: yes, God (﷾) speaks and acts. | Jain teaching: no; each soul must rely on its own effort. |
Test 1: Does it say it comes from God (﷾)?
Many holy books fail this first test, because they never say that God (﷾) sent them. A teacher may be wise. But if he does not say that his words came from God (﷾), they are not God's (﷾) message. A dream or a strong feeling cannot stand in for this test, since people of every faith report them.
“And then these verses, which were neither supernaturally inspired, nor learned before in the past, occurred to me:”
Jaini writes that the authority of the Jain teachings rests ultimately on the fact that they were preached by an omniscient being. Jain teachers claim that only the teachings of the Jina can stand the scrutiny of reason (p. 89).
Jaini writes that the Jaina, who does not hold to a God acting in the world, cannot lean on faith in divine grace. He has to rely largely on his own initiative and effort, for his needs in this world and for his salvation (p. 89).
Reports a second-century CE account by Ban Gu that the Analects was compiled by the first and second generations of Confucius's disciples and then handed down privately for centuries. Notes that the classicist Zhu Weizheng argued in 1986 that the Analects is neither quoted nor named before the second century BCE, the century in which its text was fixed, and that excavated copies date from the first century BCE. Suggests the Analects may in part be a selection from a larger and more varied body of Confucius-related material.
Sima Qian's chapter on Laozi says he was Li Er, also called Dan, a man of Chu who kept the archives at the Zhou court. Laozi cultivated the Way and virtue, and his learning aimed at hiding himself and having no name. When he left Zhou, the keeper of a pass asked him to write a book. So he wrote a book in two parts, of some five thousand words, on the meaning of the Way and virtue. Then he left, and no one knows where he ended. The chapter then gives other accounts. Some say it was Lao Laizi, also a man of Chu, who wrote fifteen chapters on the uses of the Taoist teaching. It records that the Grand Historian of Zhou, also named Dan but written with a different character, met Duke Xian of Qin long after Confucius died. Some say this Dan was Laozi, some say not, and no one knows whether it is so. It calls Laozi a gentleman who lived hidden from the world.

“So in the dimness of the great commencement, we, by relying on the original teaching, learn the time of the conception of the earth and of the birth of islands; in the remoteness of the original beginning, we, by trusting the former sages, perceive the era of the genesis of Deities and of the establishment of men.”
“The Hindus have received their religion through their revelation, the Vedas. They hold that the Vedas are without beginning and without end. It may sound ludicrous to this audience, how a book can be without beginning or end. But by the Vedas no books are meant. They mean the accumulated treasury of spiritual law discovered by different persons in different times. Just as the law of gravitation existed before its discovery, and would exist if all humanity forgot it, so with the laws that govern the spiritual world. The moral, ethical and spiritual relation between soul and souls and between individual spirits and the Father of all spirits were there before their discovery and would remain even if we forgot them. The discoverers of these laws are called Rishis, and we honor them as perfected beings, and I am glad to tell this audience that some of the very best of them were women.”
“As a skilled craftsman makes a car, a singer I, Mighty One! this hymn for thee have fashioned. If thou, O Agni, God, accept it gladly, may we obtain thereby the heavenly Waters.”
“Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus,”
“And God spake all these words, saying,”
“As the word of the Lord cometh to me, so I make known, O Lalo”
“This is the Book; in it is guidance sure, without doubt, to those who fear Allah;”
“I am the vanquisher of all, the knower of all, unsullied in the midst of all things. I've given up all, freed through the ending of craving. Since I know for myself, whose follower should I be? I have no tutor. There is no one like me.”
Buddhist scripturesThe Buddha taught what he said he knew for himself: "Since I know for myself, whose follower should I be?"
Jain scripturesTheir teaching rests on an all-knowing teacher. Jains do not believe in a God who acts in the world.
Chinese classicsThe Analects are Confucius's sayings, gathered by his pupils. The Tao Te Ching was written because a gatekeeper asked for it.
Shinto booksThe Kojiki was put together in 712 on an empress's orders, "trusting the former sages".
Hindu scripturesThe Vedas are called revelation, yet the Rig Veda's own poets say they made its hymns.
New TestamentLuke says he wrote from what eyewitnesses had handed down.
Hebrew BibleThe Torah says: "And God spake all these words".
Guru Granth SahibGuru Nanak says the word of the Lord came to him.
The Qur'anIt calls itself "guidance sure, without doubt" (2:2).
- Yes
- No
- Partly
Test 2: Is it free of contradiction?
God (﷾) makes no mistakes, so His word would not contradict itself, or the world He made. Each of the other books tested here fails this test. The Qur'an asks to be tested on it: had it come from anyone but God (﷾), it says, people would have found much discrepancy in it (4:82).
“And again the anger of the Lord was kindled against Israel, and he moved David against them to say, Go, number Israel and Judah.”
“And Satan stood up against Israel, and provoked David to number Israel.”
“And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.”
“Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.”
“(At a distance of) Laksha Yojanas above the sun is seen the moon; in two fortnights it enjoys one Samvatsara of the sun, in two days and a quarter one month and in one day one Paksha of the sun; sometimes its speed becomes quicker than that of the sun.”
The Moon is an average of 238,855 miles (384,400 kilometres) from the Earth. The Sun, the solar system's only star, is about 93 million miles (150 million kilometres) from the Earth, so it is about 390 times farther away than the Moon.
“They then together produced the Sun-Goddess, who was called Oho-hiru-me no muchi.”
“In one writing it is said:—"Izanagi no Mikoto said: 'I wish to procreate the precious child who is to rule the world.' He therefore took in his left hand a white-copper mirror, upon which a Deity was produced from it called Oho-hiru-me no Mikoto.”
“Thereafter, a Deity was produced by his washing his left eye, which was called Ama-terasu-no-oho-Kami.”
Jaini reports that the Svetambaras hold that Mahavira married the princess Yasoda and fathered a daughter, while the Digambaras believe he remained a bachelor throughout his life (p. 11). On clothing, he writes that the Digambaras believe Mahavira and the other Jinas went without clothing at all times after their renunciation, and that every Jain monk must do the same. In the Svetambara account Mahavira wore a cloth for a time before going without clothing, and the Svetambaras do not require their monks to go without clothing. Jaini calls this doubtless the single most important point of contention between the two traditions (p. 13).
In a note on Mahavira's family, Jacobi records that the story of the transfer of Mahavira's embryo from the womb of the Brahmin woman Devananda to that of the Kshatriya woman Trisala is rejected by the Digambaras, while the Svetambaras uphold its truth. He adds that the story is found in the Acaranga, the Kalpa Sutra and many other books.
“All things are not-self— when this is seen with wisdom, one grows disillusioned with suffering: this is the path to purity.”
“And what is the burden? The five grasping aggregates, it should be said. What five? The grasping aggregates of form, feeling, perception, choices, and consciousness. This is called the burden. And who is the bearer of the burden? The individual, it should be said; the venerable of such name and such clan. This is called the bearer of the burden.”
“P.—Surely then the person is known in the sense of a real and ultimate fact? Th.—Granting that the Exalted One said that which is quoted, is that a reason for affirming that the person is known in the sense of a real and ultimate fact?”
“Say not that the Hindu and Musalman books are false; false is he who reflecteth not on them. If you say that the one God is in everything, then why kill fowls?”
“Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.”
Hebrew Bible2 Samuel says the LORD moved David to count Israel. 1 Chronicles says Satan did.
New TestamentMatthew says Judas "went and hanged himself". Acts says that "falling headlong, he burst asunder in the midst".
Hindu scripturesThe Bhagavata Purana puts the moon above the sun. In fact the moon is far nearer to us.
Shinto booksThe Nihon Shoki gives three different accounts of how the Sun Goddess came to be.
Jain scripturesJainism's two branches tell Mahavira's life in two ways: married with a daughter, or never married.
Buddhist scripturesThey say all things are "not-self", yet the Buddha calls "the individual" the one who carries the burden. Early Buddhist schools split over what this means.
Guru Granth SahibIt says the Hindu and Muslim books are not false, though they teach opposite things.
Chinese classicsNot needed: neither book says it is from God (﷾).
The Qur'anIt asks for this test: had it come from anyone but God (﷾), people would have found much discrepancy in it (4:82).
- Yes
- No
- Not needed
Test 3: Was it kept as it was given?
If people changed a message, no one could tell God's (﷾) words from theirs. Every other book tested here falls short, at least in part: parts were lost, the text was changed, or scholars still argue over the wording. The Qur'an warns of those who write the Book with their own hands and then say, "This is from Allah" (2:79). Of itself, it says that God (﷾) will guard it (15:9). It was learned by heart and written down while the Prophet (ﷺ) lived, and gathered into one volume soon after his death.
“How do ye say, We are wise, and the law of the Lord is with us? Lo, certainly in vain made he it; the pen of the scribes is in vain.”
Sorts the biblical Dead Sea Scrolls into groups. Some are close to the medieval Masoretic text; some follow the Hebrew text behind the Greek Septuagint, among them 4QJer-b, which has the shorter form of Jeremiah; some are close to the Samaritan Pentateuch; and many follow none of these. The Great Isaiah Scroll differs from the Masoretic text in many small details of spelling and grammar, while agreeing with it in content in most places.
On the ending of Mark, reports that verses 9-20 are missing from the two oldest Greek manuscripts, Sinaiticus and Vaticanus, and from some early translations; that Clement of Alexandria and Origen show no knowledge of them; and that Eusebius and Jerome say the passage was absent from almost all the Greek copies they knew.
Jamison and Witzel write that the Rig Veda has come down basically in only one extremely well preserved school, that of Shakalya, whose word-by-word analysis of the text (the Padapatha) is also handed down; the Bashkala and Mandukeya collections are lost. Their table of Vedic texts lists the surviving collections: one of the Rig Veda, three of the Sama Veda, six of the Yajur Veda (one of them partial) and two of the Atharva Veda, which they say differ considerably from each other. The table marks other texts as lost, such as the Paippalada school's Brahmana, which has no surviving text.
Witzel judges Patanjali's list of schools (21 of the Rig Veda, 101 of the Yajur Veda, 1,000 of the Sama Veda, 9 of the Atharva Veda) to be clearly unrealistic in part (p. 259, n. 10). He notes that other Rig Veda versions, now lost, such as that of the Bashkala school, had more hymns and ended with a different hymn; only the Shakala Rig Veda ends with the hymn it has today (p. 265, n. 32). He compares them there with the Rig Veda's apocryphal hymns (the Khila collection), which he describes on pp. 284-285 as handed down as a separate collection only in Kashmir. He also describes early Yajur Veda texts known only from fragments, among them the now lost Caraka Samhita (p. 298).
“we are told by the Svetambaras, as well as the Digambaras, that besides the Angas, there existed other and probably older works, called Purvas, of which there were originally fourteen. The knowledge of these Purvas was gradually lost, till at last it became totally extinct.”
“The text of the three pitakas and the atthakatha thereon did the most wise bhikkhus hand down in former times orally, but since they saw that the people were falling away (from religion) the bhikkhus came together, and in order that the true doctrine might endure, they wrote them down in books.”
Geiger, the chronicle's translator, gives about 483 BCE as the probable year of the Buddha's death, and stresses that the date is only approximate. He places the beginning of the second half of King Vattagamani's reign at the end of 29 or the beginning of 28 BCE, and his return to the throne about ten years earlier by the chronicle's own figures.
“The Bhikkhus of the Great Council settled a doctrine contrary (to the true Faith). Altering the original redaction they made another redaction. They transposed Suttas which belonged to one place (of the collection), to another place; they destroyed the (true) meaning and the Faith, in the Vinaya and in the five Collections (of Suttas).”

“I hear that the chronicles of the emperors and likewise the original words in the possession of the various families deviate from exact truth, and are mostly amplified by empty falsehoods.”
Says Guru Arjan and his scribe Bhai Gurdas completed the first edition, the Adi Granth, in 1604 and installed it in the Golden Temple at Amritsar. Its hymns are chiefly by six of the Gurus, with others by Hindu bhakti saints and the Sufi Sheikh Farid. Guru Gobind Singh later added the hymns of Guru Tegh Bahadur to make the final edition. The article reports a scholarly debate over two early manuscripts: at one place the Kartarpur manuscript has only the two opening lines of a hymn of Guru Arjan, followed by blank folios, while the Banno manuscript, dated 1644, has the whole hymn. Scholars disagree which reflects the original.
“Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby.”
“We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).”
Zayd ibn Thabit reports that after many who knew the Qur'an by heart were killed at Yamama, Abu Bakr asked him to gather the Qur'an into one volume, reminding him that he used to write down the revelation for the Messenger of Allah. Zayd collected it from written pieces and from the memories of men, and the finished copy passed from Abu Bakr to Umar and then to Hafsa.

Test 4: A proof that no one can match
The first three tests can only rule a book out. Passing them does not prove that a book is from God (﷾): a careful writer can avoid contradiction, and printing can keep any book. So the test that decides is a proof that no human being can match. None of the other scriptures sets a challenge like this. The Qur'an does. It challenges anyone in doubt to produce one surah like it, and to call on any helpers they have besides Allah (2:23). It speaks of the heavens and the earth, the sea, the womb and the nations of the past, yet it repeats none of the mistaken beliefs of its age. So the question is not only what it got right, but all that it could have got wrong, and did not.
“And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true.”
“Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.”
“And I will make thee like the top of a rock: thou shalt be a place to spread nets upon; thou shalt be built no more: for I the Lord have spoken it, saith the Lord God.”
“Son of man, Nebuchadrezzar king of Babylon caused his army to serve a great service against Tyrus: every head was made bald, and every shoulder was peeled: yet had he no wages, nor his army, for Tyrus, for the service that he had served against it:”
“Him God raised up the third day, and shewed him openly; Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead.”
Hebrew BibleIt sets no challenge to match it. It points to prophecy, yet Ezekiel's word that Tyre would be built no more did not come true.
New TestamentIt sets no challenge to match it. The proof it points to, the risen Jesus, was shown "not to all the people, but unto witnesses chosen before of God".
Hindu, Jain, Buddhist, Chinese, Shinto and Sikh booksNone of them sets a test like this.
The Qur'anIt dares anyone in doubt to make one surah like it, and to call on any helpers they have besides Allah (2:23).
Test 5: Is it within reach?
A God who will judge every people would make His message known to them. The Qur'an says that God (﷾) sent a warner to every people, and that He punishes no one until a messenger has come. Today the Qur'an is recited, printed and translated in every land, and the Arabic it was given in is still spoken. Anyone can read it and put it to the tests above.
“Verily We have sent thee in truth, as a bearer of glad tidings, and as a warner: and there never was a people, without a warner having lived among them (in the past).”
“Who receiveth guidance, receiveth it for his own benefit: who goeth astray doth so to his own loss: No bearer of burdens can bear the burden of another: nor would We visit with Our Wrath until We had sent a messenger (to give warning).”
The Qur'an asks to be tested
The Qur'an makes all five claims about itself, and asks to be judged by them. No other scripture does. The page "Why is Islam true?" tests these claims one by one, and "How can we tell if a holy book really comes from God?" sets out the tests in full.
“This is the Book; in it is guidance sure, without doubt, to those who fear Allah;”
“Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.”
“We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).”
Zayd ibn Thabit reports that after many who knew the Qur'an by heart were killed at Yamama, Abu Bakr asked him to gather the Qur'an into one volume, reminding him that he used to write down the revelation for the Messenger of Allah. Zayd collected it from written pieces and from the memories of men, and the finished copy passed from Abu Bakr to Umar and then to Hafsa.
“And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true.”
“Verily We have sent thee in truth, as a bearer of glad tidings, and as a warner: and there never was a people, without a warner having lived among them (in the past).”
“Who receiveth guidance, receiveth it for his own benefit: who goeth astray doth so to his own loss: No bearer of burdens can bear the burden of another: nor would We visit with Our Wrath until We had sent a messenger (to give warning).”
Says it is from God (﷾)It calls itself a Book in which there is no doubt (2:2).
Free of contradictionIt says a book from anyone but God (﷾) would hold much discrepancy (4:82).
Kept as givenLearned by heart and written down while the Prophet (ﷺ) lived; God (﷾) promised to guard it (15:9).
A proof no one can matchMake one surah like it, if you are in doubt (2:23).
Within reach of everyoneA warner was sent to every people (35:24). Today the Qur'an is read and translated in every land.
Perspectives
Too many religions to know
Many sceptics say there are so many religions that no one can know which, if any, is true. Every believer already rejects all the others, they say, and the atheist just rejects one more.
Every believer already rejects nearly all the religions and gods there are. With so many to choose from, the reasonable view is that none of them is true.
Rebuttal
Many wrong answers to a sum do not show that it has no answer. No one needs to check every religion. A message from God (﷾) must say it is from Him, must not contradict itself, must be kept, must bring proof no one can match, and must be within reach. Not every religion even claims the first. The Qur'an claims all five, and asks to be tested.
Every religion sees part of the truth
Many Hindus, and many others, say that truth is one, and that each religion sees part of it. They often tell the story of blind men touching one elephant: each feels a different part, and each is partly right.
The Rig Veda says the sages give many names to what is One. Like blind men touching one elephant, each religion grasps part of the same truth.
Rebuttal
In one of its oldest tellings, in the Buddhist Udana, the story makes the opposite point. The blind men are all wrong, and they come to blows. Only someone who can see knows what the elephant is. To say that every religion holds part of the truth, a person would need to see the whole elephant himself. And religions do not describe parts of one thing. One says God (﷾) is One, another that there are many gods, and another that there is no Creator at all. These cannot all be true. The Qur'an says truth stands out clear from error.
The Islamic perspective
Truth can be known, because God (﷾) made His message clear and within reach of every people. A message from Him says so, holds no contradiction, is kept, and brings proof no one can match. The Qur'an makes all these claims and invites anyone to test them.
The Qur'an asks people to bring their proof, and says truth stands out clear from error.
The Qur'an says that if it were from anyone but God (﷾), people would find much discrepancy in it.
The Qur'an challenges anyone in doubt to produce one surah like it, and says God (﷾) will guard it.
God (﷾) sent a warner to every people, and punishes no one before a messenger has come.
