The freed slave of Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him), who was the overseer of his properties in Ta'if, said: Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) said to me: What do you do with the zakah of my wealth? He said: I give some of it to the ruler (sultan) and some of it I give in charity. He said: What do they do with it? He said: They buy cloth with it, with which they marry women, and they also acquire land with it. He said: Give it back to them, for the Prophet (peace and blessings be upon him) commanded us "to give it back to them, and their reckoning is upon them."
