The word(s) "gain" appears 258 time(s) in 240 verse(s) in Quran in Muhammad Pickthal translation.

(161) And Allah repulsed the disbelievers in their wrath; they gained no good. Allah averted their attack from the believers. Allah is ever Strong, Mighty.

(162) Thou canst defer whom thou wilt of them and receive unto thee whom thou wilt, and whomsoever thou desirest of those whom thou hast set aside (temporarily), it is no sin for thee (to receive her again); that is better; that they may be comforted and not grieve, and may all be pleased with what thou givest them. Allah knoweth what is in your hearts (O men), and Allah is ever Forgiving, Clement.

(163) If the hypocrites, and those in whose hearts is a disease, and the alarmists in the city do not cease, We verily shall urge thee on against them, then they will be your neighbours in it but a little while.

(164) He will adjust your works for you and will forgive you your sins. Whosoever obeyeth Allah and His messenger, he verily hath gained a signal victory.

(165) But those who strive against Our revelations, challenging (Us), theirs will be a painful doom of wrath.

(166) And he had no warrant whatsoever against them, save that We would know him who believeth in the Hereafter from him who is in doubt thereof; and thy Lord (O Muhammad) taketh note of all things.

(167) And as for those who strive against Our revelations, challenging, they will be brought to the doom.

(168) Lo! those who read the Scripture of Allah, and establish worship, and spend of that which We have bestowed on them secretly and openly, they look forward to imperishable gain,

(169) We sent not down against his people after him a host from heaven, nor do We ever send.

(170) To warn whosoever liveth, and that the word may be fulfilled against the disbelievers.
