The word(s) "gain" appears 364 time(s) in 322 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Those who believe, then reject faith, then believe (again) and (again) reject faith, and go on increasing in unbelief,- Allah will not forgive them nor guide them nor guide them on the way.

(52) (These are) the ones who wait and watch about you: if ye do gain a victory from Allah, they say: "Were we not with you?"- but if the unbelievers gain a success, they say (to them): "Did we not gain an advantage over you, and did we not guard you from the believers?" but Allah will judge betwixt you on the Day of Judgment. And never will Allah grant to the unbelievers a way (to triumphs) over the believers.

(53) O ye who believe! Take not for friends unbelievers rather than believers: Do ye wish to offer Allah an open proof against yourselves?

(54) What can Allah gain by your punishment, if ye are grateful and ye believe? Nay, it is Allah that recogniseth (all good), and knoweth all things.

(55) And for their covenant we raised over them (the towering height) of Mount (Sinai); and (on another occasion) we said: "Enter the gate with humility"; and (once again) we commanded them: "Transgress not in the matter of the sabbath." And we took from them a solemn covenant.

(56) That they rejected Faith; that they uttered against Mary a grave false charge;

(57) And there is none of the People of the Book but must believe in him before his death; and on the Day of Judgment he will be a witness against them;-

(58) Messengers who gave good news as well as warning, that mankind, after (the coming) of the messengers, should have no plea against Allah: For Allah is Exalted in Power, Wise.

(59) O ye who believe! Call in remembrance the favour of Allah unto you when certain men formed the design to stretch out their hands against you, but (Allah) held back their hands from you: so fear Allah. And on Allah let believers put (all) their trust.

(60) In blasphemy indeed are those that say that Allah is Christ the son of Mary. Say: "Who then hath the least power against Allah, if His will were to destroy Christ the son of Mary, his mother, and all every - one that is on the earth? For to Allah belongeth the dominion of the heavens and the earth, and all that is between. He createth what He pleaseth. For Allah hath power over all things."
