A man once said to the Prophet Muhammad (peace be upon him): "I have plenty of property, a large family, a great deal of money, and I am a gracious host to my guests. Tell me how to conduct my life and how to spend (my money)." The Prophet replied: "Give (regular charity) out of your property, for truly it is a purifier, and be kind to your relatives and acknowledge the rights of the poor, neighbors and (those in need who seek your help)."
