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

(51) "Our Lord! Grant us what You promised unto us through Your Messengers and disgrace us not on the day of Resurrection, for You never break (Your) Promise."

(52) And (also) those who spend of their substance to be seen of men, and believe not in Allah and the Last day [they are the friends of Shaitan (Satan)], and whoever takes Shaitan (Satan) as an intimate; then what a dreadful intimate he has!

(53) And what loss have they if they had believed in Allah and in the Last day, and they spend out of what Allah has given them for sustenance? And Allah is Ever All-Knower of them.

(54) On that day those who disbelieved and disobeyed the Messenger (Muhammad صلى الله عليه وسلم) will wish that they were buried in the earth, but they will never be able to hide a single fact from Allah.

(55) O you who believe! Obey Allah and obey the Messenger (Muhammad صلى الله عليه وسلم), and those of you (Muslims) who are in authority. (And) if you differ in anything amongst yourselves, refer it to Allah and His Messenger (صلى الله عليه وسلم), if you believe in Allah and in the Last day. That is better and more suitable for final determination.

(56) Allah! La ilaha illa Huwa (none has the right to be worshipped but He). Surely, He will gather you together on the day of Resurrection about which there is no doubt. And who is truer in statement than Allah?

(57) Lo! You are those who have argued for them in the life of this world, but who will argue for them on the day of Resurrection against Allah, or who will then be their defender?

(58) O you who believe! Believe in Allah, and His Messenger (Muhammad صلى الله عليه وسلم), and the Book (the Qur'an) which He has sent down to His Messenger, and the Scripture which He sent down to those before (him); and whosoever disbelieves in Allah, His Angels, His Books, His Messengers, and the Last day, then indeed he has strayed far away.

(59) Those (hypocrites) who wait and watch about you; if you gain a victory from Allah, they say: "Were we not with you?" But if the disbelievers gain a success, they say (to them): "Did we not gain mastery over you and did we not protect you from the believers?" Allah will judge between you (all) on the day of Resurrection. And never will Allah grant to the disbelievers a way (to triumph) over the believers.

(60) And for their covenant, We raised over them the Mount and (on the other occasion) We said: "Enter the gate prostrating (or bowing) with humility;" and We commanded them: "Transgress not (by doing worldly works) on the Sabbath (Saturday)." And We took from them a firm covenant .
