Mukhtasar Bukhari

Narrated from Sayyiduna Ka’b bin ‘Ujrah (may Allah be pleased with him) that (the Companions) said, “O Messenger of Allah! We have learned how to send peace upon you (i.e., it is recited in at-Tahiyyat), but how should we send blessings (salat) upon you?” The Prophet (peace and blessings be upon him) said: “Say: O Allah! Send mercy upon Muhammad (peace be upon him) and upon the family of Muhammad, as You sent mercy upon the family of Ibrahim (peace be upon him). Indeed, You are Praiseworthy and Glorious. (And) O Allah! Send blessings upon Muhammad (peace be upon him) and upon the family of Muhammad, as You sent blessings upon the family of Ibrahim (peace be upon him). Indeed, You are Praiseworthy and Glorious.”
