Bethink thee of the leaders of the Children of Israel after Moses, how they said unto a prophet whom they had: Set up for us a king and we will fight in Allah's way. He said: Would ye then refrain from fighting if fighting were prescribed for you? They said: Why should we not fight in Allah's way when we have been driven from our dwellings with our children? Yet, when fighting was prescribed for them, they turned away, all save a few of them. Allah is aware of evil-doers.
