This prayer is taken from Sayyidi Habib Umar bin Hafiz’s collection of prayers using Allah’s beautiful names in which he calls upon Allah by His beautiful names and then asks Him to bestow prayers upon His Beloved by those names. Finally, he asks Allah for a portion of those attributes which belong to Allah and which He has bestowed upon His Messenger ﷺ.
اللَّهُمَّ يا اللهُ يا بَرُّ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ البَرِّ و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و كُنْ لنا بِهِ بَرَّاً رَؤُوفاً
O Allah, the Beneficent, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the beneficent Prophet and upon his Family and Companions, and by him be beneficent and kind to us.
