The word(s) "repentance" appears 76 time(s) in 69 verse(s) in Quran in Mohsin Khan translation.

(41) That Allah may reward the men of truth for their truth (i.e. for their patience at the accomplishment of that which they covenanted with Allah), and punish the hypocrites, if He wills, or accept their repentance by turning to them (in Mercy). Verily, Allah is Oft-Forgiving, Most Merciful.

(42) So that Allah will punish the hypocrites, men and women, and the men and women who are Al-Mushrikun (polytheists, idolaters, pagans, disbelievers, in the Oneness of Allah, and His Messenger Muhammad صلى الله عليه وسلم). And Allah will pardon (accept the repentance of) the true believers of the Islamic Monotheism, men and women. And Allah is Ever Oft-Forgiving, Most Merciful.

(43) See they not what is before them and what is behind them, of the heaven and the earth? If We will, We shall sink the earth with them, or cause a piece of the heaven to fall upon them. Verily, in this is a sign for every slave who turns to Allah in repentance (i.e. the one who believes in the Oneness of Allah and performs deeds of His obedience and always begs His Pardon).

(44) And they will say (in the Hereafter): "We do believe (now):" but how could they receive (Faith and the acceptance of their repentance by Allah) from a place so far off (i.e. to return to the worldly life again).

(45) And a barrier will be set between them and that which they desire [i.e. At-Taubah (turning to Allah in repentance) and the accepting of Faith], as was done in the past with the people of their kind. Verily, they have been in grave doubt.

(46) 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).

(47) [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.

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

(49) 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).

(50) "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)!
