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

(311) "We never heard (the like) of this among the people of these latter days: this is nothing but a made-up tale!"

(312) These (today) only wait for a single mighty Blast, which (when it comes) will brook no delay.

(313) They say: "Our Lord! hasten to us our sentence (even) before the day of Account!"

(314) It was We that made the hills declare, in unison with him, Our Praises, at eventide and at break of day,

(315) O David! We did indeed make thee a vicegerent on earth: so judge thou between men in truth (and justice): Nor follow thou the lusts (of thy heart), for they will mislead thee from the Path of Allah: for those who wander astray from the Path of Allah, is a Penalty Grievous, for that they forget the day of Account.

(316) Such is the Promise made, to you for the day of Account!

(317) "And My curse shall be on thee till the day of Judgment."

(318) (Iblis) said: "O my Lord! Give me then respite till the day the (dead) are raised."

(319) "Till the day of the Time Appointed."

(320) He created the heavens and the earth in true (proportions): He makes the Night overlap the day, and the day overlap the Night: He has subjected the sun and the moon (to His law): Each one follows a course for a time appointed. Is not He the Exalted in Power - He Who forgives again and again?
