سنن ابن ماجه

It was narrated from 'Abdullah bin Buraidah that : 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."
