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 مانِعُ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ حصنك المانع الحصين و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً وامْنَعْ بِهِ عَنِّي جَمِيعَ الأَسْوَاءِ مَنْعاً
O Allah, the Preventer, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the Prophet, Your impenetrable fortress and upon his Family and Companions, and by him prevent any type of harm coming to me.
