‘Abd ar-Rahrman b. Abu Laila said that Ka‘b b. ‘Ujra met him and asked if he would like him to present him with something he had heard from the Prophet. He expressed his desire to hear it, and he said:We asked God’s Messenger this question,“How is blessing to be invoked on you who belong to the prophetic family? God has taught us [only] how to salute you.”He told us to say,“O God, bless Muhammad and Muhammad’s family as Thou didst bless Abraham and Abraham’s family. Thou art indeed praiseworthy and glorious. O God, grant favours to Muhammad and Muhammad’s family as Thou didst grant favours to Abraham and Abraham’s family. Thou art indeed praiseworthy and glorious.”(Bukhari and Muslim, but Muslim did not mention Abraham in the two places.)
