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

(121) And of the bedouins there are some who believe in Allah and the Last day, and look upon what they spend in Allah's Cause as means of nearness to Allah, and a cause of receiving the Messenger's invocations. Indeed these (spendings in Allah's Cause) are a means of nearness for them. Allah will admit them to His Mercy. Certainly Allah is Oft-Forgiving, Most Merciful.

(122) Never stand you therein. Verily, the mosque whose foundation was laid from the first day on piety is more worthy that you stand therein (to pray). In it are men who love to clean and to purify themselves. And Allah loves those who make themselves clean and pure [i.e. who clean their private parts with dust (which has the properties of soap) and water from urine and stools, after answering the call of nature].

(123) Surely, your Lord is Allah Who created the heavens and the earth in six days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(124) Verily, in the alternation of the night and the day and in all that Allah has created in the heavens and the earth are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for those people who keep their duty to Allah, and fear Him much.

(125) And when Our clear Verses are recited unto them, those who hope not for their meeting with Us, say: "Bring us a Qur'an other than this, or change it." Say (O Muhammad صلى الله عليه وسلم): "It is not for me to change it on my own accord; I only follow that which is revealed unto me. Verily, I fear the torment of the Great day (i.e. the day of Resurrection) if I were to disobey my Lord."

(126) Verily, the likeness of (this) worldly life is as the water (rain) which We send down from the sky; so by it arises the intermingled produce of the earth of which men and cattle eat: until when the earth is clad in its adornments and is beautified, and its people think that they have all the powers of disposal over it, Our Command reaches it by night or by day and We make it like a clean-mown harvest, as if it had not flourished yesterday! Thus do We explain the Ayat (proofs, evidence, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect.

(127) And the day whereon We shall gather them all together, then We shall say to those who did set partners in worship with Us: "Stop at your place! You and your partners (whom you had worshipped in the worldly life)." then We shall separate them, and their (Allah's so-called) partners shall say: "It was not us that you used to worship."

(128) And on the day when He shall gather (resurrect) them together, (it will be) as if they had not stayed (in the life of this world and graves) but an hour of a day. They will recognise each other. Ruined indeed will be those who denied the Meeting with Allah, and were not guided.

(129) And they say: "When will be this promise (the torment or the day of Resurrection), if you speak the truth?"

(130) Say: "Tell me, if His torment should come to you by night or by day, which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on ?"
