Rabi’ah bin Shayban says: I said to Sayyiduna Hasan bin Ali (may Allah be pleased with him): Do you remember anything special from the Messenger of Allah (peace and blessings be upon him)? He said: Once the Messenger of Allah (peace and blessings be upon him) took me to the storehouse of zakat. I picked up a date from there and put it in my mouth. The Messenger of Allah (peace and blessings be upon him) said: Throw it away, for it is not lawful for the Messenger of Allah (peace and blessings be upon him) or any member of his household.
