رَضِيتُ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا
It was narrated from Abu Salam, the servant of the Last Prophet Muhammad (Sallaho Alaihi wa Aalihi Wasallim), that:
the Prophet (Sallaho Alaihi wa Aalihi Wasallim) said: There is no Muslim - or no person, or slave (of Allah) - who says, in the morning and evening: Radaytu billahi Rabban wa bil-Islami dinan wa bi Muhammadin nabiyyan (I am content with Allah as my Lord, Islam as my religion and Muhammad as my Prophet), but he will have a promise from Allah to make him pleased on the Day of Resurrection.
