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 قُدُّوس صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ المُقَدَّس و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً و قَدِّسْنِي بِهِتَقْدِيساً
Allāhumma yā Allāhu yā Quddūs ṣalli ‘alā ‘adika wa ḥabībika sayyidinā Muḥammad an-nabī al-muqaddas wa ‘ali ālihi wa ṣaḥbihi wa sallim tasliman wa qaddisnī bihi taqdīsā.
O Allah, O Transcendent, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the Prophet purified from all imperfection and by him purify me from all imperfection.
