وَما تَفَرَّقَ الَّذينَ أوتُوا الكِتابَ إِلّا مِن بَعدِ ما جاءَتهُمُ البَيِّنَةُ

And those who were given the book did not divide, except after the proof had come to them.

EXEGESIS

Tafarraqa (divide) is derived from the root faraqa, meaning to separate. Tafarraqa is the emphatic second form of the verb, intending to separate distinctly and completely. The word firqah derives from the same root and is used to refer to a sect, especially in a religious context.

EXPOSITION

After delineating the nature of the bayyinah, namely the Prophet and his purified revelation, the surah now turns to the reaction of the communities mentioned in verse 1. This verse may be interpreted in two ways: contextually, or as a general historical phenomenon.

Contextually, Tabatabai explains that the verse marks a transition from description to consequence. Once the proof was revealed, those who had previously anticipated such a messenger did not unite upon recognising him; rather, discord intensified.^{‎[1]Mizan, 20/338.} The expression mā tafarraqū (did not divide) employs negation followed by exception – illā min baʿdi mā jāʾathum al‑bayyinah (except after the proof had come to them) – to signal that their division was not from ignorance or lack of evidence, but occurred in defiance of evidence, after unmistakable clarification had reached them.

The verse illustrates the Quranic principle that revelation itself becomes a criterion, separating hearts according to intention. Those whose motives were sincere found confirmation in the Prophet’s message, whereas those protecting worldly position and inherited bias recoiled from truth, even though they acknowledged its clarity. The bayyinah thus acts as a decisive test (tamḥīṣ): it unveils the moral substance of belief, turning a person’s hidden and latent opposition into outright rejection and separation.

Tabatabai connects this phenomenon with the divine law mentioned in verse 1. There he described the phenomenon of God’s sustained and constant practice of guiding peoples until proof is delivered to them, as well as other Quranic passages asserting that division among the People of the Book arose from envy and desire for precedence, not from ambiguity in revelation (cf. 2:213, 42:14).^{‎[2]Mizan, 20/338.} This verse illustrates that the coming of the Prophet did not create confusion, but exposed the internal corruption and self‑interest that already existed. Their discord after receiving the proof was in reality the manifestation of inner rejection that had long been concealed beneath outward religiosity.

There is however a key question here. Why does verse 1 mention both the People of the Book and the polytheists together, while verse 4 speaks only of those who were given the book?

Tabatabai believes that the phrase those who were given the book in verse 4 is broader than the People of the Book (verse 1). All of humanity in some sense has received divine guidance, but different groups responded differently – some forgot it, some altered it, and some preserved and believed in it. Therefore, those who were given the book can be read as including the polytheists along with the Jews and Christians. Both had once received aspects of divine revelation and then became divided after the truth was made clear.^{‎[3]Mizan. 20/338-339.}

The other less likely interpretation asserts that the verse presents a general historical phenomenon. The division mentioned in the verse intends tafarraqū ʿan al-islām; meaning they did not separate from Islam and become different religions, such as Judaism or Christianity, until after they rejected the divine messages that came to them reminding them of islām, which is the original religion of all mankind, Indeed, with Allah religion is islām, and those who were given the book did not differ except after knowledge had come to them (3:19). Islām here is meant in the general sense of the divine religion that has been brought by all prophets, as mentioned in the next verse of this surah. Thus, for example, God describes the followers of Prophet Jesus (a), saying, But they fragmented their religion among themselves, each party exulting in what it had (23:53). Some claimed Jesus (a) was God, some claimed Mary was God, some believed in a trinity of ‘Father, Son, and Holy Ghost’ and so on; all of this occurred after they had been given the religion of islām by Prophet Jesus (a).

The emphasis that this division did not occur except after the proof had come to them is to point out that despite being given proof, they corrupted and twisted their faith. The difference with verse 1 is that there the verse spoke of them rejecting the message of Islam brought by Prophet Muhammad (s), whilst in this verse it speaks of them corrupting the message brought by previous prophets such as Prophet Jesus (a) and Prophet Moses (a), and inventing new religions.

Based on this interpretation, it becomes clear why the polytheists are not mentioned in this verse. The discussion here is about how all the various sects of the People of the Book are actually corruptions of the teachings of the prophets they claim to follow.

The next verse clarifies and highlights the simplicity of the core message of Islam that was given to them by their prophets, which serves to emphasise amazement at how such a simple core message about worshipping God could, for example, be twisted to worshipping the prophet who had brought that message.

REVIEW OF TAFSĪR LITERATURE

Ṭūsī points out a debate that has been sparked by this verse. Some interpreters have pointed to this verse as evidence that a kāfir is not born a kāfir, rather kufr only occurs after one consciously rejects the bayyinah. Critics of this view, however, have countered that this would result in the bayyinah being a mafsadah (a source of corruption), since it is the cause for them straying into kufr. This criticism completely misses the mark though, as the very point of God placing us on this earth is to test us, to see who chooses faith and righteousness and who chooses rebellion and sin. The purpose of the bayyinah is to inform us of the reality of our creation and its purpose and our duty towards our Creator, so that we may then make the choice of which path we wish to follow. Therefore it is not a mafsadah, but rather serves the most important purpose of all.
