Sunan Ibn Majah Book 5, Hadith 102
“I heard Ibn Abi Laila say: ‘Ka’b
bin
‘Ujrah met me and said: “Shall I not give you a gift? The
Messenger of Allah (ﷺ) came out to us and we said: ‘We know what
it
means to send greetings on you, but what does it mean to send
peace
and blessings upon you?’ He said: ‘Say: Allahumma salli
‘ala
Muhammadin wa ‘ala ali Muhammadin, kama sallayta ‘ala
Ibrahima, innaka
Hamidun Majid; Allahumma barik ‘ala Muhammadin wa
‘ala ali Muhammadin, kama barakta ‘ala Ibrahima,
innaka Hamidun Majid (O Allah, send your grace,
honour and mercy upon
Muhammad and upon the family of Muhammad, as
You sent Your grace,
honour and mercy upon Ibrahim, You are indeed
Praiseworthy, Most
Glorious. O Allah, send Your blessings upon
Muhammad and the family of
Muhammad, as You sent Your blessings upon
Ibrahim, You are indeed
Praiseworthy, Most Glorious).’”
“We said: ‘O Messenger of Allah! We know what it means to send greetings upon you, but what does it mean to send peace and blessings upon you?’ He said: ‘Say: “Allahumma salli ‘ala Muhammadin ‘abdika wa Rasulika kama salayta ‘ala Ibrahima, wa barik ‘ala Muhammad (wa ‘ala ali Muhammadin) kama barakta ‘ala Ibrahima [O Allah, send Your grace, honor and mercy upon Muhammad, Your slave and Messenger, as You sent Your (grace, honour and mercy) upon Ibrahim, and send Your blessings upon Muhammad (and the family of Muhammad) as You sent Your blessings upon Ibrahim].”
“O Messenger of Allah! We have been commanded to send peace and blessings upon you. How should we send peace and blessings upon you?” He said: “Say: Allahumma salli ‘ala Muhammadin wa azwajihi wa dhurriyatihi, kama sallayta ‘ala Ibrahim; wa barik ‘ala Muhammadin wa azwajihi wa dhurriyatihi kama barakta ‘ala ali Ibrahim fil-‘alamin, innaka Hamidum Majid (O Allah, send Your grace, honour and mercy upon Muhammad and his wives and offspring, as You sent Your grace, honour and mercy upon Ibrahim. O Allah, send Your blessings upon Muhammad and his wives and offspring, as You sent Your blessings upon the family of Ibrahim among the nations, You are indeed Praiseworthy, Most Glorious).”
