Musnad Ahmad 1396
It was narrated from Moosa bin Talhah, that his father said:
I said: “O Messenger of Allah(ﷺ), how do we send blessings upon you?” He said: `Say: O Allah, send Your salah (grace, honour and mercy) upon Muhammad and upon the family of Muhammad, as You sent Your salah upon the family of Ibrahim, You are indeed Praiseworthy, Most Glorious. And send Your blessings upon Muhammad and the family of Muhammad, as You sent Your blessings upon the family of Ibrahim, You are indeed Praiseworthy, Most Glorious.”
حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا مُجَمِّعُ بْنُ يَحْيَى الْأَنْصَارِيُّ، حَدَّثَنَا عُثْمَانُ بْنُ مَوْهَبٍ، عَنْ مُوسَى بْنِ طَلْحَةَ، عَنْ أَبِيهِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ كَيْفَ الصَّلَاةُ عَلَيْكَ قَالَ قُلْ اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ وَبَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ‏.‏
