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 كريمُ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ الكَرِيم و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و كَرِّمْنِي بِهِ تَكْرِيماً
Allāhumma yā Allāhu yā Karīmu ṣalli `alā `abdika wa ḥabībika sayyidinā Muḥammad an-Nabī al-karīm wa `alā ālihi wa ṣaḥbihi wa sallim taslīman wa karrimnī bi takrīmā
O Allāh, O Generous, bestow abundant prayers and peace upon Your slave and beloved, our Master Muḥammad, the generous Prophet and upon his Family and Companions, and by him pour Your generosity upon me.
