Kaʿb bin Ujrah met me and said, "Shall I not give you a present I got from the Prophet?" ʿAbdur- Rahman said, "Yes, give it to me." I said, "We asked Messenger of Allah ﷺ saying, 'O Messenger of Allah ﷺ! How should one (ask Allah to) send blessings on you, the members of the family, for Allah has taught us how to salute you (in the prayer)?' He said, 'Say: O Allah! Send Your Mercy on Muhammad and on the family of Muhammad, as You sent Your Mercy on Abraham and on the family of Abraham, for You are the Most Praise-worthy, the Most Glorious. O Allah! Send Your Blessings on Muhammad and the family of Muhammad, as You sent your Blessings on Abraham and on the family of Abraham, for You are the Most Praise-worthy, the Most Glorious.' " (Using translation from Bukhārī 3370)
أَلَا أَهْدِي لَكَ هَدِيَّةً سَمِعْتُهَا مِنَ النَّبِيِّ ﷺ فَقُلْتُ بَلَى فَأَهْدِهَا لِي قَالَ سَأَلْنَا رَسُولَ اللهِ ﷺ فَقُلْنَا يَا رَسُولَ اللهِ كَيْفَ الصَّلَاةُ عَلَيْكُمْ أَهْلَ الْبَيْتِ قَالَ قُولُوا اللهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ وَعَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ اللهُمَّ بَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ وَعَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ
