Musnad Ahmad 1018:112

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from Ibn Tawus, from Abu Bakr ibn Muhammad ibn 'Amr ibn Hazm, from a man among the companions of the Prophet, may Allah bless him and grant him peace, from the Prophet, may Allah bless him and grant him peace, that he used to say: "O Allah, send prayers upon Muhammad, and upon his household, and upon his wives, and his offspring, just as You sent prayers upon the family of Abraham; indeed, You are Praiseworthy. And bless Muhammad, and his household, and his wives, and his offspring, just as You blessed the family of Abraham; indeed, You are Praiseworthy, Glorious." Ibn Tawus said: And my father used to say the like of that.
