The word(s) "repent" appears 115 time(s) in 99 verse(s) in Quran in Mohsin Khan translation.

(71) Be patient (O Muhammad صلى الله عليه وسلم) of what they say, and remember Our slave Dawud (David), endued with power. Verily, he was ever oft-returning in all matters and in repentance (toward Allah).

(72) [Dawud (David)] said (immediately without listening to the opponent): "He has wronged you in demanding your ewe in addition to his ewes. And, verily, many partners oppress one another, except those who believe and do righteous good deeds, and they are few." And Dawud (David) guessed that We have tried him and he sought Forgiveness of his Lord, and he fell down prostrate and turned (to Allah) in repentance.

(73) And to Dawud (David) We gave Sulaiman (Solomon). How excellent a slave! Verily, he was ever oft-returning in repentance (to Us)!

(74) And indeed, We did try Sulaiman (Solomon) and We placed on his throne Jasad (a devil, so he lost his kingdom for a while) and he did return (to Allah with obedience and in repentance, and to his throne and kingdom by the Grace of Allah).

(75) "And take in your hand a bundle of thin grass and strike therewith (your wife), and break not your oath. Truly! We found him patient. How excellent a slave! Verily he was ever oft-returning in repentance (to Us)!

(76) And when some hurt touches man, he cries to his Lord (Allah Alone), turning to Him in repentance. But when He bestows a favour upon him from Himself, he forgets that for which he cried for before, and he sets up rivals to Allah, in order to mislead others from His Path. Say: "Take pleasure in your disbelief for a while: surely you are (one) of the dwellers of the Fire!"

(77) Those who avoid At-Taghut (false deities) by not worshipping them and turn to Allah (in repentance), for them are glad tidings; so announce the good news to My slaves -

(78) Those who listen to the Word [good advice La ilaha illallah - (none has the right to be worshipped but Allah) and Islamic Monotheism] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut) those are (the ones) whom Allah has guided and those are men of understanding.

(79) "And turn in repentance and in obedience with true Faith (Islamic Monotheism) to your Lord and submit to Him (in Islam) before the torment comes upon you, (and) then you will not be helped.

(80) The Forgiver of sin, the Acceptor of repentance, the Severe in punishment, the Bestower (of favours). La ilaha illa Huwa (none has the right to be worshipped but He), to Him is the final return.
