The word(s) "day" appears 569 time(s) in 514 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Allah! There is no god but He: of a surety He will gather you together against the day of Judgment, about which there is no doubt. And whose word can be truer than Allah's?

(52) Ah! These are the sort of men on whose behalf ye may contend in this world; but who will contend with Allah on their behalf on the day of Judgment, or who will carry their affairs through?

(53) O ye who believe! Believe in Allah and His Messenger, and the scripture which He hath sent to His Messenger and the scripture which He sent to those before (him). Any who denieth Allah, His angels, His Books, His Messengers, and the day of Judgment, hath gone far, far astray.

(54) (These are) the ones who wait and watch about you: if ye do gain a victory from Allah, they say: "Were we not with you?"- but if the unbelievers gain a success, they say (to them): "Did we not gain an advantage over you, and did we not guard you from the believers?" but Allah will judge betwixt you on the day of Judgment. And never will Allah grant to the unbelievers a way (to triumphs) over the believers.

(55) And there is none of the People of the Book but must believe in him before his death; and on the day of Judgment he will be a witness against them;-

(56) But those among them who are well-grounded in knowledge, and the believers, believe in what hath been revealed to thee and what was revealed before thee: And (especially) those who establish regular prayer and practise regular charity and believe in Allah and in the Last day: To them shall We soon give a great reward.

(57) Forbidden to you (for food) are: dead meat, blood, the flesh of swine, and that on which hath been invoked the name of other than Allah; that which hath been killed by strangling, or by a violent blow, or by a headlong fall, or by being gored to death; that which hath been (partly) eaten by a wild animal; unless ye are able to slaughter it (in due form); that which is sacrificed on stone (altars); (forbidden) also is the division (of meat) by raffling with arrows: that is impiety. This day have those who reject faith given up all hope of your religion: yet fear them not but fear Me. This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion. But if any is forced by hunger, with no inclination to transgression, Allah is indeed Oft-forgiving, Most Merciful.

(58) This day are (all) things good and pure made lawful unto you. The food of the People of the Book is lawful unto you and yours is lawful unto them. (Lawful unto you in marriage) are (not only) chaste women who are believers, but chaste women among the People of the Book, revealed before your time,- when ye give them their due dowers, and desire chastity, not lewdness, nor secret intrigues if any one rejects faith, fruitless is his work, and in the Hereafter he will be in the ranks of those who have lost (all spiritual good).

(59) From those, too, who call themselves Christians, We did take a covenant, but they forgot a good part of the message that was sent them: so we estranged them, with enmity and hatred between the one and the other, to the day of judgment. And soon will Allah show them what it is they have done.

(60) As to those who reject Faith,- if they had everything on earth, and twice repeated, to give as ransom for the penalty of the day of Judgment, it would never be accepted of them, theirs would be a grievous penalty.
