Sunan an-Nasa'i 1290

Ishaq ibn Ibrahim informed us: Muhammad ibn Bishr informed us: Mujammi‘ ibn Yahya narrated to us, from ‘Uthman ibn Mawhab, from Musa ibn Talhah, from his father, who said: We said, “O Messenger of Allah, how should we invoke blessings upon you?” He said: “Say: ‘O Allah, send blessings upon Muhammad and the family of Muhammad, as You sent blessings upon Ibrahim and the family of Ibrahim. You are indeed Praiseworthy, Glorious. And bless Muhammad and the family of Muhammad, as You blessed Ibrahim and the family of Ibrahim. You are indeed Praiseworthy, Glorious.’”
