The word(s) "gain" appears 351 time(s) in 314 verse(s) in Quran in Mohsin Khan translation.

(51) And there is none of the people of the Scripture (Jews and Christians) but must believe in him ['Îsa (Jesus), son of Maryam (Mary), as only a Messenger of Allah and a human being] before his ['Îsa (Jesus) عليه السلام) or a Jew's or a Christian's] death (at the time of the appearance of the angel of death). And on the Day of Resurrection, he ['Îsa (Jesus)] will be a witness against them.

(52) Messengers as bearers of good news as well as of warning in order that mankind should have no plea against Allah after the (coming of) Messengers. And Allah is Ever All-Powerful, All-Wise.

(53) O you who believe! Remember the Favour of Allah unto you when some people desired (made a plan) to stretch out their hands against you, but (Allah) held back their hands from you. So fear Allah. And in Allah let the believers put their trust.

(54) Surely, in disbelief are they who say that Allah is the Messiah, son of Maryam (Mary) . Say (O Muhammad صلى الله عليه وسلم): "Who then has the least power against Allah, if He were to destroy the Messiah, son of Maryam (Mary), his mother, and all those who are on the earth together?" And to Allah belongs the dominion of the heavens and the earth, and all that is between them. He creates what He wills. And Allah is Able to do all things.

(55) "If you do stretch your hand against me to kill me, I shall never stretch my hand against you to kill you : for I fear Allah, the Lord of the 'Alamin (mankind, jinn, and all that exists)."

(56) The recompense of those who wage war against Allah and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off from opposite sides, or be exiled from the land. That is their disgrace in this world, and a great torment is theirs in the Hereafter.

(57) Verily, those who disbelieve, if they had all that is in the earth, and as much again therewith to ransom themselves thereby from the torment on the Day of Resurrection, it would never be accepted of them, and theirs would be a painful torment.

(58) O Messenger (Muhammad صلى الله عليه وسلم)! Let not those who hurry to fall into disbelief grieve you, of such who say: "We believe" with their mouths but their hearts have no faith. And of the Jews are men who listen much and eagerly to lies - listen to others who have not come to you. They change the words from their places; they say, "If you are given this, take it, but if you are not given this, then beware!" And whomsoever Allah wants to put in Al-Fitnah [error, because of his rejecting of Faith], you can do nothing for him against Allah. Those are the ones whose hearts Allah does not want to purify (from disbelief and hypocrisy); for them there is a disgrace in this world, and in the Hereafter a great torment.

(59) They thought there will be no Fitnah (trial or punishment), so they became blind and deaf; after that Allah turned to them (with Forgiveness); yet again many of them became blind and deaf. And Allah is the All-Seer of what they do.

(60) Those who believe and do righteous good deeds, there is no sin on them for what they ate (in the past), if they fear Allah (by keeping away from His forbidden things), and believe and do righteous good deeds, and again fear Allah and believe, and once again fear Allah and do good deeds with Ihsan (perfection). And Allah loves the good-doers.
