The word(s) "sins" appears 134 time(s) in 127 verse(s) in Quran in Mohsin Khan translation.

(1) This is the Book (the Qur'an), whereof there is no doubt, a guidance to those who are Al-Muttaqun [the pious believers of Islamic Monotheism who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allah much (perform all kinds of good deeds which He has ordained)].

(2) And (remember) when We said: "Enter this town (Jerusalem) and eat bountifully therein with pleasure and delight wherever you wish, and enter the gate in prostration (or bowing with humility) and say: 'Forgive us,' and We shall forgive you your sins and shall increase (reward) for the good-doers."

(3) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(4) Shaitan (Satan) threatens you with poverty and orders you to commit Fahsha (evil deeds, illegal sexual intercourse, sins); whereas Allah promises you Forgiveness from Himself and Bounty, and Allah is All-Sufficient for His creatures' needs, All-Knower.

(5) If you disclose your Sadaqat (alms-giving), it is well; but if you conceal them and give them to the poor, that is better for you. (Allah) will expiate you some of your sins. And Allah is Well-Acquainted with what you do.

(6) Like the behaviour of the people of Fir'aun (Pharaoh) and those before them; they belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). So Allah seized (destroyed) them for their sins. And Allah is Severe in punishment.

(7) Those who say: "Our Lord! We have indeed believed, so forgive us our sins and save us from the punishment of the Fire."

(8) Say (O Muhammad صلى الله عليه وسلم to mankind): "If you (really) love Allah then follow me (i.e. accept Islamic Monotheism, follow the Qur'an and the Sunnah), Allah will love you and forgive you your sins. And Allah is Oft-Forgiving, Most Merciful."

(9) Indignity is put over them wherever they may be, except when under a covenant (of protection) from Allah, and from men; they have drawn on themselves the Wrath of Allah, and destruction is put over them. This is because they disbelieved in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah and killed the Prophets without right. This is because they disobeyed (Allah) and used to transgress beyond bounds (in Allah's disobedience, crimes and sins).

(10) And those who, when they have committed Fahishah (illegal sexual intercourse) or wronged themselves with evil, remember Allah and ask forgiveness for their sins; - and none can forgive sins but Allah - and do not persist in what (wrong) they have done, while they know.
