The word(s) "gain" appears 419 time(s) in 395 verse(s) in Quran in Muhammad Habib Shakir translation.

(171) And he said: O my sons! do not (all) enter by one gate and enter by different gates and I cannot avail you aught against Allah; judgment is only Allah's; on Him do I rely, and on Him let those who are reliant rely.

(172) And when they had entered as their father had bidden them, it did not avail them aught against Allah, but (it was only) a desire in the soul of Yaqoub which he satisfied; and surely he was possessed of knowledge because We had given him knowledge, but most people do not know.

(173) They said: Are you indeed Yusuf? He said: I am Yusuf and this is my brother; Allah has indeed been gracious to us; surely he who guards (against evil) and is patient (is rewarded) for surely Allah does not waste the reward of those who do good.

(174) He said: (There shall be) no reproof against you this day; Allah may forgive you, and He is the most Merciful of the merciful.

(175) Take this my shirt and cast it on my father's face, he will (again) be able to see, and come to me with all your families.

(176) So when the bearer of good news came he cast it on his face, so forthwith he regained his sight. He said: Did I not say to you that I know from Allah what you do not know?

(177) And We have not sent before you but men from (among) the people of the towns, to whom We sent revelations. Have they not then travelled in the land and seen what was the end of those before them? And certainly the abode of the hereafter is best for those who guard (against evil); do you not then understand?

(178) They shall have chastisement in this world's life, and the chastisement of the hereafter is certainly more grievous, and they shall have no protector against Allah.

(179) A likeness of the garden which the righteous are promised; there now beneath it rivers, its food and shades are perpetual; this is the requital of those who guarded (against evil), and the requital of the unbelievers is the fire.

(180) And thus have We revealed it, a true judgment in Arabic, and if you follow their low desires after what has come to you of knowledge, you shall not have against Allah any guardian or a protector.
