“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).’” (Using translation from Ibn Mājah 904)  

أَلَا أُهْدِي إلَيكَ هَدِيَّةً؟ إِنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ عَلَيْنَا فَقُلْنَا قَدْ عَلِمْنَا كَيْفَ السَّلَامُ عَلَيْكَ فَكَيْفَ نُصَلِّي عَلَيْكَ؟ قَالَ قُولُوا اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ وَبَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ  

"The Messenger of Allah ﷺ came to us in the Majlis of Sa'd bin 'Ubadah and Bashir bin Sa'd said to him: 'Allah has commanded us to send Salah upon you, O Messenger of Allah; so how should we send salah upon you?' The Messenger of Allah ﷺ remained silent until we wished that he had not asked him. Then he said: 'Say: 'Alahumma salli 'ala Muhammad wa 'ala ali Muhammad, kama sallaita 'ala Ibrahima wa barik 'ala Muhammad kama barakta 'ala ali Ibrahim fil-'alamin, innaka hamidun majid (O Allah, send salah upon Muhammad and upon the family of Muhammad, as You sent salah upon the family of Ibrahim, and send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon the family of Ibrahim among the nations. You are indeed Worthy of praise, Full of glory.)" And the salam is as you know.'" (Using translation from Nasāʾī 1285)   

أَنَّ مُحَمَّدَ بْنَ عَبْدِ اللَّهِ بْنِ زَيْدٍ الْأَنْصَارِيَّ الَّذِي كَانَ أُرِيَ النِّدَاءَ بِالصَّلَاةِ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ أَخْبَرَهُ أَنَّ أَبَا مَسْعُودٍ الْأَنْصَارِيَّ قَالَ أَتَانَا رَسُولُ اللَّهِ ﷺ فَجَلَسَ مَعَنَا فِي مَجْلِسِ سَعْدِ بْنِ عُبَادَةَ فَقَالَ لَهُ بَشِيرُ بْنُ سَعْدٍ وَهُوَ أَبُو النُّعْمَانِ بْنُ بَشِيرٍ أَمَرَنَا اللَّهُ أَنْ نُصَلِّيَ عَلَيْكَ يَا رَسُولَ اللَّهِ فَكَيْفَ نُصَلِّي عَلَيْكَ؟ قَالَ فَصَمَتَ رَسُولُ اللَّهِ ﷺ حَتَّى تَمَنَّيْنَا أَنَّهُ لَمْ يَسْأَلْهُ ثُمَّ قَالَ قُولُوا اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ وَبَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ فِي الْعَالَمِينَ إِنَّكَ حَمِيدٌ مَجِيدٌ وَالسَّلَامُ كَمَا قَدْ عَلِمْتُمْ
