(a) Abd al-Rahman bin Abi Layla (may Allah have mercy on him) says: Ka'b bin Ujrah (may Allah be pleased with him) met me and said: Shall I not give you a gift? Then he said: The Messenger of Allah (peace and blessings be upon him) came out to us, and we said to him: O Messenger of Allah, we have come to know how to send salam upon you, but tell us how we should send blessings upon you. He (peace and blessings be upon him) said: "Say: 'Allahumma salli 'ala Muhammadin wa 'ala ali Muhammad, kama sallayta 'ala Ibrahim, innaka Hamidun Majid. Allahumma barik 'ala Muhammadin wa 'ala ali Muhammad, kama barakta 'ala Ibrahim, innaka Hamidun Majid' (O Allah, send Your mercy upon Muhammad (peace and blessings be upon him) and upon his family, just as You sent mercy upon Ibrahim (peace be upon him); indeed, You are Praiseworthy and Glorious. O Allah, send down blessings upon Muhammad (peace and blessings be upon him) and upon the family of Muhammad too, just as You sent down blessings upon Ibrahim (peace be upon him); indeed, You are Praiseworthy, Glorious)."
(b) In al-Bukhari there are the words 'kama barakta 'ala Ibrahim' (just as You sent down blessings upon Ibrahim).
(c) The words of the hadith "we have come to know how to send salam upon you" refer to sending salam upon the Prophet (peace and blessings be upon him) in the tashahhud, and likewise the Companion's words "so how should we send blessings upon you" were also a question about the blessings in the tashahhud.
