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

(11) Allah accepts only the repentance of those who do evil in ignorance and foolishness and repent soon afterwards; it is they whom Allah will forgive and Allah is Ever All-Knower, All-Wise.

(12) And of no effect is the repentance of those who continue to do evil deeds until death faces one of them and he says: "Now I repent;" nor of those who die while they are disbelievers. For them We have prepared a painful torment.

(13) Allah wishes to make clear (what is lawful and what is unlawful) to you, and to show you the ways of those before you, and accept your repentance, and Allah is All-Knower, All-Wise.

(14) Allah wishes to accept your repentance, but those who follow their lusts, wish that you (believers) should deviate tremendously away (from the Right Path).

(15) We sent no Messenger, but to be obeyed by Allah's Leave. If they (hypocrites), when they had been unjust to themselves, had come to you (Muhammad صلى الله عليه وسلم) and begged Allah's Forgiveness, and the Messenger had begged forgiveness for them: indeed, they would have found Allah All-Forgiving (One Who forgives and accepts repentance), Most Merciful.

(16) It is not for a believer to kill a believer except (that it be) by mistake; and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood-money, i.e. Diya) be given to the deceased's family unless they remit it. If the deceased belonged to a people at war with you and he was a believer, the freeing of a believing slave (is prescribed); and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood-money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise.

(17) Except those who repent (from hypocrisy), do righteous good deeds, hold fast to Allah, and purify their religion for Allah (by worshipping none but Allah, and do good for Allah's sake only, not to show off), then they will be with the believers. And Allah will grant the believers a great reward.

(18) Except for those who (having fled away and then) came back (as Muslims) with repentance before they fall into your power; in that case, know that Allah is Oft-Forgiving, Most Merciful.

(19) But whosoever repents after his crime and does righteous good deeds (by obeying Allah), then verily, Allah will pardon him (accept his repentance). Verily, Allah is Oft-Forgiving, Most Merciful.

(20) Will they not turn with repentance to Allah and ask His Forgiveness? For Allah is Oft-Forgiving, Most Merciful.
