'Amr ibn al-'As said, "The Prophet, may Allah bless him and grant him peace, sent for me. He commanded me to put on my clothes and weapons and come to him. I did that and came to him while he was doing wudu'. He looked at me and then lowered his eyes. He then said, ''Amr, I want to put you in charge of an army and Allah will give you booty. I will give you a correct portion of the spoils.' I said, 'I did not become Muslim out of the desire for property. I became Muslim out of the desire for Islam and so that I would be with the Messenger of Allah, may Allah bless him and grant him peace.' He said, ''Amr! Sound (legitimately acquired) wealth is very excellent for a righteous man!'"
