The word(s) "repent" appears 62 time(s) in 60 verse(s) in Quran in Muhammad Pickthal translation.

(21) They swear by Allah that they said nothing (wrong), yet they did say the word of disbelief, and did disbelieve after their Surrender (to Allah). And they purposed that which they could not attain, and they sought revenge only that Allah by His messenger should enrich them of His bounty. If they repent it will be better for them; and if they turn away, Allah will afflict them with a painful doom in the world and the Hereafter, and they have no protecting friend nor helper in the earth.

(22) Know they not that Allah is He Who accepteth repentance from His bondmen and taketh the alms, and that Allah is He Who is the Relenting, the Merciful.

(23) (Triumphant) are those who turn repentant (to Allah), those who serve (Him), those who praise (Him), those who fast, those who bow down, those who fall prostrate (in worship), those who enjoin the right and who forbid the wrong and those who keep the limits (ordained) of Allah - And give glad tidings to believers!

(24) And to the three also (did He turn in mercy) who were left behind, when the earth, vast as it is, was straitened for them, and their own souls were straitened for them till they bethought them that there is no refuge from Allah save toward Him. Then turned He unto them in mercy that they (too) might turn (repentant unto Him). Lo! Allah! He is the Relenting, the Merciful.

(25) See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they heed.

(26) And (bidding you): Ask pardon of your Lord and turn to Him repentant. He will cause you to enjoy a fair estate until a time appointed. He giveth His bounty unto every bountiful one. But if ye turn away, lo! (then) I fear for you the retribution of an awful Day.

(27) And, O my people! Ask forgiveness of your Lord, then turn unto Him repentant; He will cause the sky to rain abundance on you and will add unto you strength to your strength. Turn not away, guilty!

(28) And unto (the tribe of) Thamud (We sent) their brother Salih. He said: O my people! Serve Allah, Ye have no other Allah save Him. He brought you forth from the earth and hath made you husband it. So ask forgiveness of Him and turn unto Him repentant. Lo! my Lord is Nigh, Responsive.

(29) He said: O my people! Bethink you: if I am (acting) on a clear proof from my Lord and He sustaineth me with fair sustenance from Him (how can I concede aught to you)? I desire not to do behind your backs that which I ask you not to do. I desire naught save reform so far as I am able. My welfare is only in Allah. In Him I trust and unto Him I turn (repentant).

(30) Ask pardon of your Lord and then turn unto Him (repentant). Lo! my Lord is Merciful, Loving.
