The word(s) "repentance" appears 34 time(s) in 34 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) And remember Moses said to his people: "O my people! Ye have indeed wronged yourselves by your worship of the calf: So turn (in repentance) to your Maker, and slay yourselves (the wrong-doers); that will be better for you in the sight of your Maker." Then He turned towards you (in forgiveness): For He is Oft-Returning, Most Merciful.

(2) But those who reject Faith after they accepted it, and then go on adding to their defiance of Faith,- never will their repentance be accepted; for they are those who have (of set purpose) gone astray.

(3) Allah accept the repentance of those who do evil in ignorance and repent soon afterwards; to them will Allah turn in mercy: For Allah is full of knowledge and wisdom.

(4) Of no effect is the repentance of those who continue to do evil, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous.

(5) Never should a believer kill a believer; but (If it so happens) by mistake, (Compensation is due): If one (so) kills a believer, it is ordained that he should free a believing slave, and pay compensation to the deceased's family, unless they remit it freely. If the deceased belonged to a people at war with you, and he was a believer, the freeing of a believing slave (Is enough). If he belonged to a people with whom ye have treaty of Mutual alliance, compensation should be paid to his family, and a believing slave be freed. For those who find this beyond their means, (is prescribed) a fast for two months running: by way of repentance to Allah: for Allah hath all knowledge and all wisdom.

(6) When Moses came to the place appointed by Us, and his Lord addressed him, He said: "O my Lord! show (Thyself) to me, that I may look upon thee." Allah said: "By no means canst thou see Me (direct); But look upon the mount; if it abide in its place, then shalt thou see Me." When his Lord manifested His glory on the Mount, He made it as dust. And Moses fell down in a swoon. When he recovered his senses he said: "Glory be to Thee! to Thee I turn in repentance, and I am the first to believe."

(7) Know they not that Allah doth accept repentance from His votaries and receives their gifts of charity, and that Allah is verily He, the Oft-Returning, Most Merciful?

(8) Those that turn (to Allah) in repentance; that serve Him, and praise Him; that wander in devotion to the cause of Allah,: that bow down and prostrate themselves in prayer; that enjoin good and forbid evil; and observe the limit set by Allah;- (These do rejoice). So proclaim the glad tidings to the Believers.

(9) See they not that they are tried every year once or twice? Yet they turn not in repentance, and they take no heed.

(10) Every soul that hath sinned, if it possessed all that is on earth, would fain give it in ransom: They would declare (their) repentance when they see the penalty: but the judgment between them will be with justice, and no wrong will be done unto them.
