Sayyidi Habib Umar bin Hafiz was asked for a simple prayer upon the Prophet ﷺ that it is easy to recite consistently
He advised reciting this prayer which he received from his teacher, Habib Muhammad bin `Alawi bin Shihab:
اللَّهُمَّ صَلِّ وسَلِّمْ على سَيِّدِنا مُحَمَّدٍ النَّبِيِّ الأُمِّي بِعَدَدِ عِلْمِك
Allahumma salli wa sallim `ala sayyidina Muhammad annabiyyi’l ummi bi `adadi `ilmik
O Allah, bestow prayers and peace upon our Master Muhammad, the Unlettered Prophet according to the extent of Your knowledge.
