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 مُتَكَبِّر صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ أَعْظَمِ الخَلْقِ تَوَاضُعَاً لَكَ و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و نَقِّنِي بِهِ عَنْ شَوَائِبِ الكِبْرِ و ارْزُقْني تَوَاضُعَاً عَظِيماً
Allāhumma yā Allāhu yā Mutakabbir ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad a’ẓami‘l-khalqi tawāḍu’an laka wa ‘alā ālihi wa ṣaḥbihi wa sallim tasliman wa naqqinī bihi ‘an shawā’ibi’l-kibri w’arzuqnī tawāḍu’an ‘aẓīma
O Allah, O Justly Proud, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the one who has humbled himself to you the most and upon his Family and Companions and by him purify me from the contamination of arrogance and bless me with immense humility.
