Prayers upon the Prophet after tashahhud
اللّهُـمَّ صَلِّ عَلـى مُحمَّـد، وَعَلـى آلِ...
اللّهُـمَّ صَلِّ عَلـى مُحمَّـد، وَعَلـى آلِ مُحمَّد، كَمـا صَلَّيـتَ عَلـى إبْراهـيمَ وَعَلـى آلِ إبْراهـيم، إِنَّكَ حَمـيدٌ مَجـيد، اللّهُـمَّ بارِكْ عَلـى مُحمَّـد، وَعَلـى آلِ مُحمَّـد، كَمـا بارِكْتَ عَلـى إبْراهـيمَ وَعَلـى آلِ إبْراهيم، إِنَّكَ حَمـيدٌ مَجـيد
Allahumma salli AAala Muhammad, wa-AAala ali Muhammad, kama sallayta AAala Ibraheema wa-AAala ali Ibraheem, innaka Hameedun Majeed, allahumma barik AAala Muhammad, wa-AAala ali Muhammad, kama barakta AAala Ibraheema wa-AAala ali Ibraheem, innaka Hameedun Majeed
