Musnad Ahmad 941:45

'Arim ibn al-Fadl narrated to us, Mu'tamir narrated to us, from his father, who said: I heard Abu Tamimah narrating from Abu 'Uthman al-Nahdi, and Abu 'Uthman was narrating it from Usamah ibn Zayd, who said: The Prophet of Allah, peace and blessings of Allah be upon him, used to take me and seat me on his thigh, and he would seat al-Hasan ibn 'Ali on his other thigh. Then he would embrace us both and say: "O Allah, have mercy upon them, for I have mercy upon them." 'Ali ibn al-Madini said: He is al-Sulaymi from 'Anazah to Rabi'ah, meaning Abu Tamimah al-Sulaymi.
