The word(s) "day-" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Say: To whom belongs what is in the heavens and the earth? Say: To Allah; He has ordained mercy on Himself; most certainly He will gather you on the resurrection day-- there is no doubt about it. (As for) those who have lost their souls, they will not believe.

(2) And whoever shall turn his back to them on that day-- unless he turn aside for the sake of fighting or withdraws to a company-- then he, indeed, becomes deserving of Allah's wrath, and his abode is hell; and an evil destination shall it be.
