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.

O you who believe! do not enter the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-- but when you are invited, enter, and when you have taken the food, then disperse-- not seeking to listen to talk; surely this gives the Prophet trouble, but he forbears from you, and Allah does not forbear from the truth And when you ask of them any goods, ask of them from behind a curtain; this is purer for your hearts and (for) their hearts; and it does not behove you that you should give trouble to the Messenger of Allah, nor that you should marry his wives after him ever; surely this is grievous in the sight of Allah.

He it is Who caused those who disbelieved of the followers of the Book to go forth from their homes at the first banishment you did not think that they would go forth, while they were certain that their fortresses would defend them against Allah; but Allah came to them whence they did not expect, and cast terror into their hearts; they demolished their houses with their own hands and the hands of the believers; therefore take a lesson, O you who have eyes!
