And hasten to forgiveness from your Lord, and a Garden the extensiveness of which is the heavens and the earth, prepared for those who guard against evil. (3:132)

And whoever does evil, and oppresses his soul, then seeks forgiveness of Allah, he will find Allah to be Forgiving, Merciful. (4:110)

The Prophet Muhammad (saw) has taught us many words of repentance and it is good if we learn, understand, and use them. Of these one has been mentioned as Syed-ul-Istighfar (the master of forgiveness). A hadith explains its extraordinary significance: "If a believer says this with complete faith and sincerity in the morning and dies before that evening, he will enter paradise. If he says it during the night and dies before the morning, he will enter paradise."

"O Allah! You are my Lord. There is no God except You. You created me and I am Your slave. To the best of my ability, I will abide by my covenant and pledge to You. I seek Your protection from the evil of my own creation. I acknowledge Your favors to me and I admit my sins. So please forgive me for no one can forgive sins except You."
