O you who believe! when you go to war in Allah's way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world's life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what you do.

And even if We had sent down to them the angels and the dead had spoken to them and We had brought together all things before them, they would not believe unless Allah pleases, but most of them are ignorant.

Have they not travelled in the earth and seen how was the end of those before them? They were stronger than these in prowess, and dug up the earth, and built on it in greater abundance than these have built on it, and there came to them their messengers with clear arguments; so it was not beseeming for Allah that He should deal with them unjustly, but they dealt unjustly with their own souls.

Has not the time yet come for those who believe that their hearts should be humble for the remembrance of Allah and what has come down of the truth? And that they should not be like those who were given the Book before, but the time became prolonged to them, so their hearts hardened, and most of them are transgressors.
