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

(1) Those who wait for (some misfortune to befall) you then If you have a victory from Allah they say: Were we not with you? And if there is a chance for the unbelievers, they say: Did we not acquire the mastery over you and defend you from the believers? So Allah shall Judge between you on the day of resurrection, and Allah will by no means give the unbelievers a way against the believers.

(2) And if they intend to act unfaithfully towards you, so indeed they acted unfaithfully towards Allah before, but He gave (you) mastery over them; and Allah is Knowing, Wise.

(3) And thus did We give to Yusuf power in the land-- he had mastery in it wherever he liked; We send down Our mercy on whom We please, and We do not waste the reward of those who do good.

(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.
