Islam has taken care of the poor and the needy.
Islam has commanded us to treat them well and make them happy.
Allah commands to give them money and food and assumed that simple annual payments would be made to them according to the ability of the donor, so that the poor would be equal with others.
Therefore (The prophet Muhammed ) did not save anything from his money, due to giving charity, at a moment in his life he suffered from hunger for ten days of mercy for the poor.
