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 سَلام صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ السَّلام و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و سَلِّمْنِي بِهِ و لَقِّني به تَحِيَّةً و سلاماً
Allāhumma yā Allāhu yā Salām ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad an-nabī as-salām wa ‘alā ālihi wa ṣaḥbihi wa sallim tasliman wa sallimnī bihi wa laqqinī bihi taḥiyyatan wa salāmā
O Allah, O Flawless One, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the Prophet of Peace and by him grant me safety and allow me to receive salutations and peace (in Paradise).
