Then after grief He sent down security on you, slumber overcoming a party of you, while (there was) another party whom their own souls had rendered anxious -- they entertained about Allah thoughts of ignorance quite unjustly. They said: Have we any hand in the affair? Say: The affair is wholly (in the hands) of Allah. They hide within their souls that which they would not reveal to thee. 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 have gone forth to the places where they would be slain. And (this happened) that Allah might test what was in your breasts and that He might purge what was in your hearts. And Allah is Knower of what is in the breasts.
