Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated: Dates of charity were presented to the Messenger of Allah (peace and blessings be upon him). He (peace be upon him) lifted Hasan or Husayn (may Allah be pleased with them both) onto his shoulder, and their saliva began to flow. He saw that there was a date from the charity dates in their mouth. So he shook them, and they spat it out. The Messenger of Allah (peace and blessings be upon him) said: "Do you not know, charity is not lawful for us."
