Sayyiduna Abu Hurairah (may Allah be pleased with him) says: We were present with the Messenger of Allah (peace and blessings be upon him) while he was distributing dates of charity, and Sayyiduna Hasan bin Ali (may Allah be pleased with him) was in his (peace be upon him) lap. When the Messenger of Allah (peace and blessings be upon him) finished his work, he lifted Sayyiduna Hasan (may Allah be pleased with him) onto his shoulder, and his saliva began to flow onto the Messenger of Allah (peace and blessings be upon him). When the Messenger of Allah (peace and blessings be upon him) raised his head and looked, he saw a date in his mouth. The Messenger of Allah (peace and blessings be upon him) put his hand into his mouth and took it out, and said: Do you not know that zakat is not lawful for the family of Muhammad (peace and blessings be upon him)?
