The word(s) "day" appears 568 time(s) in 513 verse(s) in Quran in Muhammad Pickthal translation.

(281) So set thy purpose resolutely for the right religion, before the inevitable day cometh from Allah. On that day mankind will be sundered-

(282) And on the day when the Hour riseth the guilty will vow that they did tarry but an hour - thus were they ever deceived.

(283) But those to whom knowledge and faith are given will say: The truth is, ye have tarried, by Allah's decree, until the day of Resurrection. This is the day of Resurrection, but ye used not to know.

(284) In that day their excuses will not profit those who did injustice, nor will they be allowed to make amends.

(285) Hast thou not seen how Allah causeth the night to pass into the day and causeth the day to pass into the night, and hath subdued the sun and the moon (to do their work), each running unto an appointed term; and that Allah is Informed of what ye do?

(286) O mankind! Keep your duty to your Lord and fear a day when the parent will not be able to avail the child in aught, nor the child to avail the parent. Lo! Allah's promise is the very truth. Let not the life of the world beguile you, nor let the deceiver beguile you, in regard to Allah.

(287) Allah it is Who created the heavens and the earth, and that which is between them, in six days. Then He mounted the Throne. Ye have not, beside Him, a protecting friend or mediator. Will ye not then remember?

(288) He directeth the ordinance from the heaven unto the earth; then it ascendeth unto Him in a day, whereof the measure is a thousand years of that ye reckon.

(289) So taste (the evil of your deeds). Forasmuch as ye forgot the meeting of this your day, lo! We forget you. Taste the doom of immortality because of what ye used to do.

(290) Lo! thy Lord will judge between them on the day of Resurrection concerning that wherein they used to differ.
