Hamzah bin Abdullah bin Utbah (may Allah have mercy on him) relates that he asked his father, Sayyiduna Abdullah bin Utbah bin Mas'ud (may Allah be pleased with him): "What do you remember of the Messenger of Allah (peace and blessings be upon him)?" He said: "I remember that he took me (to himself) when I was five or six years old, then he sat me in his lap, wiped my head with his blessed hand, and supplicated for blessing for me and for my children after me."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Sayyiduna Abdullah bin Utbah (may Allah be pleased with him) except with this chain, and Musa bin Awn (may Allah have mercy on him) is alone in narrating it."
