The word(s) "day" appears 704 time(s) in 579 verse(s) in Quran in Mohsin Khan translation.

(71) "And why should we not believe in Allah and in that which has come to us of the truth (Islamic Monotheism)? And we wish that our Lord will admit us (in Paradise on the day of Resurrection) along with the righteous people (Prophet Muhammad صلى الله عليه وسلم and his Companions رضي الله عنهم)."

(72) Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masakin (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn . And protect your oaths (i.e. do not swear much) . Thus Allah make clear to you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

(73) On the day when Allah will gather the Messengers together and say to them: "What was the response you received (from men to your teaching)?" They will say: "We have no knowledge, verily, only You are the All-Knower of all that is hidden (or unseen)."

(74) (Remember) when Allah will say (on the day of Resurrection). "O 'Îsa (Jesus), son of Maryam (Mary)! Remember My Favour to you and to your mother when I supported you with Ruh-ul-Qudus [Jibril (Gabriel)] so that you spoke to the people in the cradle and in maturity; and when I taught you writing, Al-Hikmah (the power of understanding), the Taurat (Torah) and the Injeel (Gospel); and when you made out of the clay a figure like that of a bird, by My Permission, and you breathed into it, and it became a bird by My Permission, and you healed those born blind, and the lepers by My Permission, and when you brought forth the dead by My Permission; and when I restrained the Children of Israel from you (when they resolved to kill you) as you came unto them with clear proofs, and the disbelievers among them said: 'This is nothing but evident magic.'"

(75) And (remember) when Allah will say (on the day of Resurrection): "O 'Îsa (Jesus), son of Maryam (Mary)! Did you say unto men: 'Worship me and my mother as two gods besides Allah?' " He will say: "Glory be to You! It was not for me to say what I had no right (to say). Had I said such a thing, You would surely have known it. You know what is in my inner-self though I do not know what is in Yours; truly, You, only You, are the All-Knower of all that is hidden (and unseen).

(76) Allah will say: "This is a day on which the truthful will profit from their truth: theirs are Gardens under which rivers flow (in Paradise) - they shall abide therein forever. Allah is pleased with them and they with Him. That is the great success (Paradise).

(77) Say (O Muhammad صلى الله عليه وسلم): "To whom belongs all that is in the heavens and the earth?" Say: "To Allah. He has prescribed Mercy for Himself. Indeed He will gather you together on the day of Resurrection, about which there is no doubt. Those who have lost themselves will not believe [in Allah as being the only Ilah (God), and Muhammad صلى الله عليه وسلم as being one of His Messengers, and in Resurrection].

(78) And to Him belongs whatsoever exists in the night and the day, and He is the All-Hearing, the All-Knowing."

(79) Say: "I fear, if I disobey my Lord, the torment of a Mighty day."

(80) He who is averted from (such a torment) on that day, (Allah) has surely been Merciful to him. And that would be the obvious success.
