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

(271) Their children and their wealth will avail them nothing against Allah. They will be the dwellers of the Fire to dwell therein forever.

(272) And those who came after them say: "Our Lord! Forgive us and our brethren who have preceded us in Faith, and put not in our hearts any hatred against those who have believed. Our Lord! You are indeed full of kindness, Most Merciful.

(273) Have you (O Muhammad صلى الله عليه وسلم) not observed the hypocrites who say to their friends among the people of the Scripture who disbelieve: "(By Allah) If you are expelled, we (too) indeed will go out with you, and we shall never obey any one against you; and if you are attacked (in fight), we shall indeed help you." But Allah is Witness that they verily are liars.

(274) They fight not against you even together, except in fortified townships, or from behind walls. Their enmity among themselves is very great. You would think they were united, but their hearts are divided. That is because they are a people who understand not.

(275) Should they gain the upper hand over you, they would behave to you as enemies, and stretch forth their hands and their tongues against you with evil, and they desire that you should disbelieve.

(276) Neither your relatives nor your children will benefit you on the Day of Resurrection (against Allah). He will judge between you. And Allah is the All-Seer of what you do.

(277) Allah does not forbid you to deal justly and kindly with those who fought not against you on account of religion nor drove you out of your homes. Verily, Allah loves those who deal with equity.

(278) It is only as regards those who fought against you on account of religion, and have driven you out of your homes, and helped to drive you out, that Allah forbids you to befriend them. And whosoever will befriend them, then such are the Zalimun (wrong-doers - those who disobey Allah).

(279) And if any of your wives have gone from you to the disbelievers, (as apostates and you asked them to return back your Mahr but they refused) - then you went out for a Ghazwah (military expedition) (against them and) gained booty; then pay from that booty to those whose wives have gone, the equivalent of what they had spent (on their Mahr ). And fear Allah in Whom you believe.

(280) And who does more wrong than the one who invents a lie against Allah, while he is being invited to Islam? And Allah guides not the people who are Zalimun (polytheists, wrong-doers and disbelievers) folk.
