Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) gave me the kunyah "Abu Hamzah". (Allamah al-Haythami says:) I say: Al-Tirmidhi has recorded from him
this report, that the Prophet (peace and blessings be upon him) gave me this kunyah because of a herb (called "hamzah") which I used to search for and pick.
Al-Tabarani recorded it; its chain contains Jabir al-Ju'fi, and he is da'if (weak).
