The word(s) "retribution" appears 10 time(s) in 9 verse(s) in Quran in Mohsin Khan translation.

(1) Aforetime, as a guidance to mankind. And He sent down the criterion [of judgement between right and wrong (this Qur'an)]. Truly, those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, for them there is a severe torment; and Allah is All-Mighty, All-Able of retribution.

(2) O you who believe! Kill not the game while you are in a state of Ihram [for Hajj or 'Umrah (pilgrimage)], and whosoever of you kills it intentionally, the penalty is an offering, brought to the Ka'bah, of an eatable animal (i.e. sheep, goat, cow) equivalent to the one he killed, as adjudged by two just men among you; or, for expiation, he should feed Masakin (poor persons), or its equivalent in Saum (fasting), that he may taste the heaviness (punishment) of his deed. Allah has forgiven what is past, but whosoever commits it again, Allah will take retribution from him. And Allah is All-Mighty, All-Able of retribution.

(3) And it is He Who has made you generations coming after generations, replacing each other on the earth. And He has raised you in ranks, some above others that He may try you in that which He has bestowed on you. Surely your Lord is Swift in retribution, and certainly He is Oft-Forgiving, Most Merciful.

(4) So We took retribution from them. We drowned them in the sea, because they belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and were heedless about them.

(5) And (remember) when your Lord declared that He would certainly keep on sending against them (i.e. the Jews), till the Day of Resurrection, those who would afflict them with a humiliating torment. Verily, your Lord is Quick in retribution (for the disobedient, wicked) and certainly He is Oft-Forgiving, Most Merciful (for the obedient and those who beg Allah's Forgiveness).

(6) So think not that Allah will fail to keep His Promise to His Messengers. Certainly, Allah is All-Mighty, All-Able of retribution.

(7) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, then turns aside therefrom? Verily, We shall exact retribution from the Mujrimun (criminals, disbelievers, polytheists, sinners).

(8) And whomsoever Allah guides, for him there will be no misleader. Is not Allah All-Mighty, Possessor of retribution?

(9) On the Day when We shall seize you with the greatest seizure (punishment). Verily, We will exact retribution.
