اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى أَزْوَاجِهِ وَذُرِّيَّتِهِ كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ، وَبَارِكْ عَلَى مُحَمَّدٍ، وَ عَلَى أَزْوَاجِهِ وَذُرِّيَّتِهِ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيمَ، إِنَّكَ حَمِيدٌ مَجِيدٌ

O Allāh, send prayers upon Muḥammad and upon the wives and descendants of Muḥammad, just as You sent prayers upon the family of Ibrāhim, and send blessings upon Muḥammad and upon the wives and descendants of Muḥammad, just as You sent blessings upon the family of Ibrāhim. Verily, You are full of praise and majesty.
