It is narrated from Hazrat Ka'b bin Ujrah (may Allah be pleased with him) that a man asked the Holy Prophet (peace and blessings be upon him), "O Messenger of Allah! We have learned how to greet you with salam, now tell us how should we send blessings (durood) upon you?" The Holy Prophet (peace and blessings be upon him) said, "Say: O Allah, send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon Ibrahim; indeed, You are Praiseworthy, Glorious. O Allah, bless Muhammad and the family of Muhammad as You blessed Ibrahim; indeed, You are Praiseworthy, Glorious."
