الصَّلَاةُ الْكَمَالِيَّة
Aṣ-Ṣalāt al-Kamāliyyah — Salawat Kamaaliyya
اَللَّهُمَّ صَلِّ وَسَلِّمْ وَبَارِكْ عَلَى سَيِّدِنَا مُحَمَّدٍ وَعَلَى آلِهِ عَدَدَ كَمَالِ اللهِ وَكَمَا يَلِيقُ بِكَمَالِهِ.
Allahumma salli wa sallim wa baarik `ala Sayyidina Muhammadin wa `ala aalihi `adada kamaalillah wa kamaa yaleequ bi kamaalih.
O Allah! Bestow Your Blessings, Peace and Grace upon our Master, Muhammad, and upon His Family according to the Perfection of Allah and as befits his perfection!
Similar to as-Salat al-Kamil, but adding alaa aalihi adada kamaalillah wa kamaa yaleequ bi kamaalihi — "on the number of Allah's Perfection" — Divine Perfection that has no less or more. It is said there is no end to the reward for this salawaat, so it cannot be measured against 600,000 or 1,000,000 salaat; its reward and benefit have no end, as Allah's Perfection has no end.
