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 وَلِيُّ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ الوَلِيِّ و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً وكُنْ لي بِهِ وَلِيَّاً نَصِيراً
Allāhumma yā Allāhu yā Waliyyu ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad an-Nabī al-walī wa ‘alā ālihi wa ṣaḥbihi wa sallim taslīman wa kun lī bihi waliyyan naṣīrā
O Allāh, O Protector, bestow abundant prayers and peace upon Your slave and beloved, our Master Muḥammad, the Prophet, the Protector, and upon his Family and Companions, and by him be my protector and supporter.
