Sunan Ibn Majah Book 34, Hadith 45
"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)."
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."
his father said: "The Messenger of Allah (saas) said: Allahumma Anta Rabbi la ilaha illa Anta, khalaqtani wa ana 'abduka wa ana 'ala 'ahdika wa wa'dika mastata'tu. A'udhu bika min sharri ma sana'tu, abu'u bi ni'matika wa abu'u bi dhanbi faghfirli, fa innahu la yaghfirudh-dhunuba illa Anta (O Allah, You are my Lord, there is none worthy of worship except You. You have created me and I am Your slave, and I am adhering to Your covenant and Your promise as much as I can. I seek refuge with You from the evil of what I do. I acknowledge Your blessing and I acknowledge my sin, so forgive me, for there is none who can forgive sin except You)."He said: "The Messenger of Allah (saas) said: 'Whoever says this by day and by night, if he dies that day or that night, he will enter Paradise if Allah wills."
