رَضِيتُ بِاللَّهِ رَبًّا، وَبِالْإِسْلَامِ دِينًا، وَبِمُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَبِيًّا
Raditu billahi Rabban, wa bil-Islami dinan, wa bi-Muhammadin sallallahu 'alayhi wa sallama Nabiyyan.
I am pleased with Allah as my Lord, with Islam as my religion, and with Muhammad (peace and blessings be upon him) as my Prophet.
Virtue
Whoever says it three times morning and evening, Allah has promised to please him on the Day of Resurrection.
