Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said to his companions one day: "Give charity." One man said: "O Messenger of Allah (peace be upon him)! I have one dinar." The Prophet (peace be upon him) said: "Spend it on yourself." He said: "If I have another?" The Prophet (peace be upon him) said: "Spend it on your wife." He said: "If I have another?" The Prophet (peace be upon him) said: "Spend it on your children." He said: "If I have another?" The Prophet (peace be upon him) said: "Spend it on your servant." He asked: "If I have another?" The Prophet (peace be upon him) said: "You know best." (Meaning, you will know yourself on whom it should be spent.)
