الصَّلَاةُ الْكَامِل
Aṣ-Ṣalāt al-Kāmil — As-Salat al-Kamil
اَللَّهُمَّ صَلِّ وَسَلِّمْ وَبَارِكْ عَلَى سَيِّدِنَا مُحَمَّدٍ وَعَلَى آلِهِ كَمَا لَا نِهَايَةَ لِكَمَالِكَ وَعَدَدَ كَمَالِهِ.
Allahumma salli wa sallim wa baarik `ala Sayyidina Muhammadin wa `ala aalihi kamaa laa nihayata li-kamaalika wa `adada kamaalih.
O Allah! Grant salawat on the Prophet ﷺ without end, on the number of perfection with which You dressed him!
The most honored salawat, which awliyaullah said one recitation equals 70,000 salawat; in the Shafiʿi school of thought they say it is "rewarded with no end," as Allah's Perfection has no end. It is read between Maghrib and ʿIsha, especially to remove forgetfulness and strengthen the memory.
