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

(111) One day He will gather them together: (It will be) as if they had tarried but an hour of a day: they will recognise each other: assuredly those will be lost who denied the meeting with Allah and refused to receive true guidance.

(112) Say: "Do ye see,- if His punishment should come to you by night or by day,- what portion of it would the sinners wish to hasten?

(113) And what think those who invent lies against Allah, of the day of Judgment? Verily Allah is full of bounty to mankind, but most of them are ungrateful.

(114) He it is That hath made you the night that ye may rest therein, and the day to make things visible (to you). Verily in this are signs for those who listen (to His Message).

(115) "This day shall We save thee in the body, that thou mayest be a sign to those who come after thee! but verily, many among mankind are heedless of Our Signs!"

(116) We settled the Children of Israel in a beautiful dwelling-place, and provided for them sustenance of the best: it was after knowledge had been granted to them, that they fell into schisms. Verily Allah will judge between them as to the schisms amongst them, on the day of Judgment.

(117) Do they then expect (any thing) but (what happened in) the days of the men who passed away before them? Say: "Wait ye then: for I, too, will wait with you."

(118) "(And to preach thus), 'Seek ye the forgiveness of your Lord, and turn to Him in repentance; that He may grant you enjoyment, good (and true), for a term appointed, and bestow His abounding grace on all who abound in merit! But if ye turn away, then I fear for you the penalty of a great day:

(119) He it is Who created the heavens and the earth in six days - and His Throne was over the waters - that He might try you, which of you is best in conduct. But if thou wert to say to them, "Ye shall indeed be raised up after death", the Unbelievers would be sure to say, "This is nothing but obvious sorcery!"

(120) If We delay the penalty for them for a definite term, they are sure to say, "What keeps it back?" Ah! On the day it (actually) reaches them, nothing will turn it away from them, and they will be completely encircled by that which they used to mock at!
