It was narrated from Abu Musa that the Prophet said: Every Muslim must give charity. It was said: What if he cannot find (anything to give)? He said: Let him work with his hands and benefit himself and give in charity. It was said: What if he cannot do that? He said: Let him help someone who is in desperate need. It was said: What if he cannot do that? He said: Let him enjoin good. It was said: What if he cannot do that? He said: Let him refrain from doing evil, for that is an act of charity.
