سنن أبي داود

Ka’b b. ‘Ujrah said: We said or the people said: Messenger of Allah, you have commanded us to invoke blessing on you and to salute you. As regards salutation we have already learnt it. How should we invoke blessing? He said: Say: “O Allah, bless Muhammad and Muhammad’s family as Thou didst bless Abraham and Abraham’s family. O Allah, grant favours to Muhammad and Muhammad’s family as Thou didst grant favours to Abraham; Thou art indeed praiseworthy and glorious.
