Sayyiduna Abu Umayrah Rushayd bin Malik (may Allah be pleased with him) narrated: We were sitting with the Messenger of Allah (peace and blessings be upon him) when a man brought him (peace and blessings be upon him) a platter of dates. He (peace and blessings be upon him) said to him: "What is this: a gift or charity?" The man said: It is charity. He (peace and blessings be upon him) said: "Then place it before the people." He said: And al-Hasan (may Allah be pleased with him) was rolling about in the dust in front of him (peace and blessings be upon him), and the child picked up a date and put it in his mouth. The Messenger of Allah (peace and blessings be upon him) noticed him, put his finger into the child's mouth and took the date out, then threw it away and said: "We, the family of Muhammad, do not eat charity."
