al-Baqara 2:92 — The claim tested against its own history

"Moses brought you clear proofs; then after him you took the calf — and you were wrongdoers."

In the previous verse it had been said: "we believe in what was sent down to us." Allegiance, that is, had been reserved to their own prophets and their own books.

This verse does not reject that claim; it tests it with its own material.

The sentence consists of three parts, and their order sets up a time-line:

The side that says "we believe in what was sent down to us" turned to something else while its own prophet was still among them, immediately after the clearest of proofs. The claim is refuted by the record of the one making it.

This is a method repeated in the sūra, and it will be seen once more at verse 94: there the claim about the hereafter will be tested by the attitude towards death. In neither is the counter-proof brought from outside; it is taken from the life of the one addressed.

The conjunction ثُمَّ in Arabic conveys tarākhī: "then", with an interval entering in between. Its use here shows that some time passed between the proof and the calf.

But the مِنۢ بَعْدِهِۦ that comes immediately after narrows that interval: "after him" — that is, right behind Moses's departure. At verse 51 of the sūra it was said how long this span was: forty nights.

Set the two notes side by side and what emerges is this: not enough time has passed for forgetting. The absence is short, the proof fresh, the turning quick.

Root ب-ي-ن: to separate two things, to distinguish. A bayyina is the proof by which truth and falsehood are separated; bayān and tabyīn are from the same root.

That the word comes in the plural matters: not a single proof but proofs. The sūra had enumerated them one by one in verses 49-60 — the parting of the sea, the shade, manna and quails, the twelve springs, water from the rock. The verse recalls this whole list with one word.

This clause at the end of the sentence is another form of the sūra's most frequently repeated clause: wa antum taʿlamūn — "and that while you know" (2/22, 2/42, 2/75, 2/188).

Here the word wrongdoing is put in the place of knowledge. In this sūra the two are bound to one another: what is done knowingly is no longer an error but an injustice. And the sense of the root ẓ-l-m, "to put a thing somewhere other than its place", occurred at the fifty-fourth verse — the setting of the calf in God's place is the word's exact counterpart.

And a nominal sentence is used: wa antum ẓālimūn — not "you did wrong" but "you were wrongdoers". In Arabic this structure states the act not as a one-off event but as the character of the condition at that moment.
