the Prophet (saas) 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."
Sunan Ibn Majah Book 34, Hadith 44
← Previous Hadith "I heard the Messenger of Allah (saas) say: "There is no person who says, in the morning and evening of every day: Bismillahil-ladhi la yadurru ma'a ismihi shay'un fil-ardi wa la fis-sama'i wa Huwas-Sami'ul-'Alim (In the name of Allah with Whose Name nothing on earth or in heaven harms, and He is the All-Seeing, All-Knowing), three times, and is then harmed by anything.'" (Hasan)He (one of the narrators) said: "Aban had been stricken with paralysis on one side of his body, and a man started looking at him. Aban said: 'Why are you looking at me? The Hadith is as I have narrated it to you, but I did not say it that day, so that the decree of Allah might be implemented.'"

Sunan Ibn Majah Book 34, Hadith 43 Next Hadith → "The Messenger of Allah (saas) never abandoned these supplications, every morning and evening: Allahumma inni as'alukal-'afwa wal-'afiyah fid-dunya wal-akhirah. Allahumma inni as'alukal-'afwa wal-'afiyah fi dini wa dunyaya wa ahli wa mali. Allahum-mastur 'awrati, wa amin raw'ati wahfazni min bayni yadayya, wa min khalfi, wa 'an yamini wa 'an shimali, wa min fawqi, wa 'audhu bika an ughtala min tahti (O Allah, I ask You for forgiveness and well-being in this world and in the Hereafter. O Allah, I ask You for forgiveness and well-being in my religious and my worldly affairs. O Allah, conceal my faults, calm my fears, and protect me from before me and behind me, from my right and my left, and from above me, and I seek refuge in You from being taken unaware from beneath me)." Waki' (one of the narrators, explaining) said: "Meaning Al-Khasf (disgrace)."
