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

(101) Verily, the number of months with Allah is twelve months (in a year), so was it ordained by Allah on the Day when He created the heavens and the earth; of them four are Sacred (i.e. the 1st, the 7th, the 11th and the 12th months of the Islamic calendar). That is the right religion, so wrong not yourselves therein, and fight against the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah) collectively as they fight against you collectively. But know that Allah is with those who are Al-Muttaqun (the pious - See V.2:2).

(102) Had it been a near gain (booty in front of them) and an easy journey, they would have followed you, but the distance (Tabuk expedition) was long for them; and they would swear by Allah, "If we only could, we would certainly have come forth with you." They destroy their ownselves, and Allah knows that they are liars.

(103) Like those before you: they were mightier than you in power, and more abundant in wealth and children. They had enjoyed their portion (awhile), so enjoy your portion (awhile) as those before you enjoyed their portion (awhile); and you indulged in play and pastime (and in telling lies against Allah and His Messenger Muhammad صلى الله عليه وسلم) as they indulged in play and pastime. Such are they whose deeds are in vain in this world and in the Hereafter. Such are they who are the losers.

(104) O Prophet (Muhammad صلى الله عليه وسلم)! Strive hard against the disbelievers and the hypocrites, and be harsh against them, their abode is Hell, - and worst indeed is that destination.

(105) There is no blame on those who are weak or ill or who find no resources to spend [in holy fighting (Jihad)], if they are sincere and true (in duty) to Allah and His Messenger. No ground (of complaint) can there be against the Muhsinun (good-doers - See the footnote of V.9:120). And Allah is Oft-Forgiving, Most Merciful.

(106) The ground (of complaint) is only against those who are rich, and yet ask exemption. They are content to be with (the women) who sit behind (at home) and Allah has sealed up their hearts (from all kinds of goodness and right guidance) so that they know not (what they are losing).

(107) And as for those who put up a mosque by way of harm and disbelief and to disunite the believers and as an outpost for those who warred against Allah and His Messenger (Muhammad صلى الله عليه وسلم) aforetime, they will indeed swear that their intention is nothing but good. Allah bears witness that they are certainly liars.

(108) Verily, Allah has purchased of the believers their lives and their properties for (the price) that theirs shall be the Paradise. They fight in Allah's Cause, so they kill (others) and are killed. It is a promise in truth which is binding on Him in the Taurat (Torah) and the Injeel (Gospel) and the Qur'an. And who is truer to his covenant than Allah? Then rejoice in the bargain which you have concluded. That is the supreme success.

(109) So who does more wrong than he who forges a lie against Allah or denies His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)? Surely, the Mujrimun (criminals, sinners, disbelievers and polytheists) will never be successful!

(110) And when We let mankind taste mercy after some adversity has afflicted them, behold! they take to plotting against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)! Say: "Allah is more Swift in planning!" Certainly, Our Messengers (angels) record all of that which you plot.
