Every Muslim must give charity. It was asked: What if one has nothing to give? The Prophet (PBUH) replied: Let him work with his hands to benefit himself and give charity. It was said: What if he is unable to do that? The Prophet (PBUH) replied: Let him help a person who is in a desperate need. It was said: What if he does not do that? The Prophet (PBUH) replied: Let him exhort about goodness and justice. It was said: What if he is unable to do that? The Prophet (PBUH) replied: Then Let him refrain from evil, for that would be as giving a charity.
