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

(41) Have they not observed what is before them and what is behind them of the sky and the earth? If We will, We can make the earth swallow them, or cause obliteration from the sky to fall on them. Lo! herein surely is a portent for every slave who turneth (to Allah) repentant.

(42) Bear with what they say, and remember Our bondman David, lord of might, Lo! he was ever turning in repentance (toward Allah).

(43) (David) said: He hath wronged thee in demanding thine ewe in addition to his ewes, and lo! many partners oppress one another, save such as believe and do good works, and they are few. And David guessed that We had tried him, and he sought forgiveness of his Lord, and he bowed himself and fell down prostrate and repented.

(44) And We bestowed on David, Solomon. How excellent a slave! Lo! he was ever turning in repentance (toward Allah).

(45) And verily We tried Solomon, and set upon his throne a (mere) body. Then did he repent.

(46) And (it was said unto him): Take in thine hand a branch and smite therewith, and break not thine oath. Lo! We found him steadfast, how excellent a slave! Lo! he was ever turning in repentance (to his Lord).

(47) And when some hurt toucheth man, he crieth unto his Lord, turning unto Him (repentant). Then, when He granteth him a boon from Him he forgetteth that for which he cried unto Him before, and setteth up rivals to Allah that he may beguile (men) from his way. Say (O Muhammad, unto such an one): Take pleasure in thy disbelief a while. Lo! thou art of the owners of the Fire.

(48) And those who put away false gods lest they should worship them and turn to Allah in repentance, for them there are glad tidings. Therefor give good tidings (O Muhammad) to My bondmen

(49) Turn unto your Lord repentant, and surrender unto Him, before there come unto you the doom, when ye cannot be helped.

(50) The Forgiver of sin, the Accepter of repentance, the Stern in punishment, the Bountiful. There is no Allah save Him. Unto Him is the journeying.
