"It was said to the Prophet ﷺ: We have been commanded to send salah and salams upon you. We know how to send salams, but how should we send salah?' 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).'" (Using translation from Nasāʾī 1286)  

قِيلَ لِلنَّبِيِّ ﷺ أُمِرْنَا أَنْ نُصَلِّيَ عَلَيْكَ وَنُسَلِّمَ فَأَمَّا السَّلَامُ فَقَدْ عَرَفْنَا فَكَيْفَ نُصَلِّي عَلَيْكَ قَالَ «قُولُوا» اللهُمَّ صَلِّ عَلَى مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ اللهُمَّ بَارِكْ عَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيمَ
