Sunan an-Nasa'i 1286

Ziyad ibn Yahya narrated to us: ‘Abd al-Wahhab ibn ‘Abd al-Majid narrated to us: Hisham ibn Hassan narrated to us, from Muhammad, from ‘Abd al-Rahman ibn Bishr, from Abu Mas‘ud al-Ansari, who said: It was said to the Prophet (ﷺ), “We have been commanded to invoke blessings upon you and to offer you greetings of peace. We already know how to offer the greeting of peace; so how should we invoke blessings upon you?” He said: “Say: ‘O Allah, send blessings upon Muhammad, as You sent blessings upon the family of Ibrahim. O Allah, bless Muhammad, as You blessed the family of Ibrahim.’”
