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 واحِدُ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ الواحِد و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً واجْعَلْنِي بِهِ رَاسِخَ القَدَمِ فيِ حَقِيقَةِ التَّوْحِيدِ مَنَّاً مِنْكَ عَظِيماً
O Allah, O One, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the unique Prophet and upon his Family and Companions, and by him bless me with complete witnessing of Your Oneness purely out of Your immense bounty.
