It was narrated from Abu Salam (RA): *the Prophet (SAW) said: "There is no Muslim - or no person, or slave (of Allah) - who says, in the morning and evening:* ‎*رَضِيتُ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا* *'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."* (Sunan Ibn Majah 3870, Book 34, Hadith 44) A very simple Dhikr to make that comes the promise of joy on the Day of Resurrection, a day when many will be in fear and a state of panic. Prepare for that day by increasing your good deeds, giving charity and doing this Dhikr in the morning and evening.
