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 خَبِيرُ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ الخَبِير و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً واجْعَلْنِي بِأَسْرَارِ ما أَوْحَيْتَهُ إِلَيْهِ خَبِيرا
Allāhumma yā Allāhu yā Khabīru ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad an-Nabī al-khabīr wa ‘alā ālihi wa ṣaḥbihi wa sallim taslīman w’aj’alnī bi asrāri mā awḥaytahu ilayhi khabīrā
O Allah, O Totally Aware, bestow abundant prayers and peace upon Your slave and beloved, our Master Muḥammad, the Prophet who has total awareness, and upon his Family and Companions, and give me total awareness of the secrets which You revealed to him.
