The word(s) "punish" appears 265 time(s) in 237 verse(s) in Quran in Mohsin Khan translation.

(11) Those who eat Riba (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitan (Satan) leading him to insanity. That is because they say: "Trading is only like Riba (usury)," whereas Allah has permitted trading and forbidden Riba (usury). So whosoever receives an admonition from his Lord and stops eating Riba (usury) shall not be punished for the past; his case is for Allah (to judge); but whoever returns [to Riba (usury)], such are the dwellers of the Fire - they will abide therein.

(12) To Allah belongs all that is in the heavens and all that is on the earth, and whether you disclose what is in your ownselves or conceal it, Allah will call you to account for it. Then He forgives whom He wills and punishes whom He wills. And Allah is Able to do all things.

(13) Allah burdens not a person beyond his scope. He gets reward for that (good) which he has earned, and he is punished for that (evil) which he has earned. "Our Lord! punish us not if we forget or fall into error, our Lord! Lay not on us a burden like that which You did lay on those before us (Jews and Christians); our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us Forgiveness. Have mercy on us. You are our Maula (Patron, Supporter and Protector, etc.) and give us victory over the disbelieving people. "

(14) It is He Who has sent down to you (Muhammad صلى الله عليه وسلم) the Book (this Qur'an). In it are Verses that are entirely clear, they are the foundations of the Book [and those are the Verses of Al-Ahkam (commandments), Al-Fara'id (obligatory duties) and Al-Hudud (legal laws for the punishment of thieves, adulterers)]; and others not entirely clear. So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings, but none knows its hidden meanings save Allah. And those who are firmly grounded in knowledge say: "We believe in it; the whole of it (clear and unclear Verses) are from our Lord." And none receive admonition except men of understanding. (Tafsir At-Tabari).

(15) 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.

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

(17) Let not the believers take the disbelievers as Auliya (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His punishment) , and to Allah is the final return.

(18) On the Day when every person will be confronted with all the good he has done, and all the evil he has done, he will wish that there were a great distance between him and his evil. And Allah warns you against Himself (His punishment) and Allah is full of kindness to (His) slaves.

(19) "As to those who disbelieve, I will punish them with a severe torment in this world and in the Hereafter, and they will have no helpers."

(20) Not for you (O Muhammad صلى الله عليه وسلم, but for Allah) is the decision; whether He turns in mercy to (pardons) them or punishes them; verily, they are the Zalimun (polytheists, disobedients, and wrong-doers).
