Sunan an-Nasa'i — Hadith #21693

It was narrated that abu Sa'eed Al-Khudri said:"We said: 'O Messenger of Allah (ﷺ), we know how to send salams upon you, but how should we send salah upon you?' He said: 'Say: "Allahumma salli 'ala Muhammadin 'abdika wa rasulika kama salaita 'ala Ibrahim wa barik 'ala Muhammadin wa 'ala ali Muhammadin kama barakta 'ala Ibrahim (O Allah, send salah upon Muhammad, Your slave and Messenger , as You sent Salah upon Ibrahim, and send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon Ibrahim)
