Hast thou not thought of the leaders of the Children of Israel after Moses? When they said to a prophet of theirs: Raise up for us a king, that we may fight in the way of Allah. He said: May it not be that you will not fight if fighting is ordained for you? They said: And what reason have we that we should not fight in Allah's way and we have indeed been deprived of our homes and our children? But when fighting was ordained for them, they turned back, except a few of them. And Allah is Knower of the wrongdoers.
