Some people asked: Messenger of Allah, how should we invoke blessings on you? He said: Say,” O Allah, bless Muhammad, his wives and his off springs, as Thou didst bless Abraham’s family, and grant favours to Muhammad’s family, his wives and off springs, as Thou didst grant favours to Abraham’s family. Thou art indeed praiseworthy and glorious. (Using translation from Abū Dāʾūd 979)  

حَدَّثَنِي أَبُو حُمَيْدٍ السَّاعِدِيُّ أَنَّهُمْ قَالُوا يَا رَسُولَ اللهِ كَيْفَ نُصَلِّي عَلَيْكَ؟ قَالَ قُولُوا اللهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَأَزْوَاجِهِ وَذُرِّيَّتِهِ كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ وَبَارِكْ عَلَى مُحَمَّدٍ وَأَزْوَاجِهِ وَذُرِّيَّتِهِ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ
