The word(s) "gained" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) 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?

(2) If you do good, you will do good for your own souls, and if you do evil, it shall be for them. So when the second promise came (We raised another people) that they may bring you to grief and that they may enter the mosque as they entered it the first time, and that they might destroy whatever they gained ascendancy over with utter destruction.

(3) Has he gained knowledge of the unseen, or made a covenant with the Beneficent Allah?

(4) The Shaitan has gained the mastery over them, so he has made them forget the remembrance of Allah; they are the Shaitan's party; now surely the Shaitan's party are the losers.
