This prayer upon the Prophet ﷺ was composed by Habib Ali al-Habashi (may Allah have mercy upon him and benefit us by him). It contains a simple but huge request: to be among those who are beloved to Allah and beloved to His Messenger ﷺ
اللَّهُمَّ صَلِّ وسَلِّمْ على سَيِّدِنا مُحَمَّدٍ ، صَلاةً نَكونُ بِها مَحْبُوبِينَ لَكَ و مَحْبُوبِينَ لَهُ
Allahumma salli wa sallim ‘ala sayyidina Muhammad salatan nakunu biha mahbubina laka wa mahbubina lahu
O Allah, bestow Your prayers and peace upon our Master Muhammad, and by these prayers make us beloved to You and beloved to him.
