It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) passed away, he (peace and blessings be upon him) was sixty-five years old.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Humayd (may Allah have mercy on him) except Bishr bin al-Mufaddal; al-Muthanna bin Mu'adh is alone in narrating it."
