The word(s) "repent" appears 60 time(s) in 58 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) See they not what is before them and behind them, of the sky and the earth? If We wished, We could cause the earth to swallow them up, or cause a piece of the sky to fall upon them. Verily in this is a Sign for every devotee that turns to Allah (in repentance).

(42) Those who had been despised will say to the arrogant ones: "Nay! it was a plot (of yours) by day and by night: Behold! Ye (constantly) ordered us to be ungrateful to Allah and to attribute equals to Him!" They will declare (their) repentance when they see the Penalty: We shall put yokes on the necks of the Unbelievers: It would only be a requital for their (ill) Deeds.

(43) Had it not been that he (repented and) glorified Allah,

(44) (David) said: "He has undoubtedly wronged thee in demanding thy (single) ewe to be added to his (flock of) ewes: truly many are the partners (in business) who wrong each other: Not so do those who believe and work deeds of righteousness, and how few are they?"... and David gathered that We had tried him: he asked forgiveness of his Lord, fell down, bowing (in prostration), and turned (to Allah in repentance).

(45) When some trouble toucheth man, he crieth unto his Lord, turning to Him in repentance: but when He bestoweth a favour upon him as from Himself, (man) doth forget what he cried and prayed for before, and he doth set up rivals unto Allah, thus misleading others from Allah's Path. Say, "Enjoy thy blasphemy for a little while: verily thou art (one) of the Companions of the Fire!"

(46) Those who eschew Evil,- and fall not into its worship,- and turn to Allah (in repentance),- for them is Good News: so announce the Good News to My Servants,-

(47) "Turn ye to our Lord (in repentance) and bow to His (Will), before the Penalty comes on you: after that ye shall not be helped.

(48) Who forgiveth sin, accepteth repentance, is strict in punishment, and hath a long reach (in all things). there is no god but He: to Him is the final goal.

(49) Those who sustain the Throne (of Allah) and those around it Sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe: "Our Lord! Thy Reach is over all things, in Mercy and Knowledge. Forgive, then, those who turn in repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire!

(50) He is the One that accepts repentance from His Servants and forgives sins: and He knows all that ye do.
