And a party of the followers of the Book say: Avow belief in that which has been revealed to those who believe, in the first part of the day, and disbelieve at the end of it, perhaps they go back on their religion.

Then after sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the breasts.

And they say: Obedience. But when they go out from your presence, a party of them decide by night upon doing otherwise than what you say; and Allah writes down what they decide by night, therefore turn aside from them and trust in Allah, and Allah is sufficient as a protector.

Lest you say that the Book was only revealed to two parties before us and We were truly unaware of what they read.
