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 مُؤْمِن صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ المُؤْمِن و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و زِدْنِي بِهِ في كُلِّ نَفَسٍ إِيمَاناً
Allāhumma yā Allāhu yā Mu’min ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad an-nabī al-mu’min wa ‘alā ālihi wa ṣaḥbihi wa sallim tasliman wa zidnī bihi fī kulli nafasin īmāna
O Allāh, O Faithful One, bestow abundant prayers and peace upon Your slave and beloved, our Master Muḥammad, the Faithful Prophet, and by him allow me to increase in faith in every breath.
