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

(251) And it is He Who gives life and causes death, and His is the alternation of night and day. Will you not then understand?

(252) "So that I may do good in that which I have left behind!" No! It is but a word that he speaks; and behind them is Barzakh (a barrier) until the day when they will be resurrected.

(253) Then, when the Trumpet is blown, there will be no kinship among them that day, nor will they ask of one another.

(254) Verily I have rewarded them this day for their patience: they are indeed the ones that are successful.

(255) They will say: "We stayed a day or part of a day. Ask of those who keep account."

(256) The fornicatress and the fornicator, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allah, if you believe in Allah and the Last day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime, but if married persons commit it (illegal sex), the punishment is to stone them to death, according to Allah's Law).

(257) On the day when their tongues, their hands, and their legs (or feet) will bear witness against them as to what they used to do.

(258) On that day Allah will pay them the recompense of their deeds in full, and they will know that Allah, He is the Manifest Truth.

(259) Allah is the Light of the heavens and the earth. The parable of His Light is as (if there were) a niche and within it a lamp: the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east (i.e. neither it gets sun-rays only in the morning) nor of the west (i.e. nor it gets sun-rays only in the afternoon, but it is exposed to the sun all day long), whose oil would almost glow forth (of itself), though no fire touched it. Light upon Light! Allah guides to His Light whom He wills. And Allah sets forth parables for mankind, and Allah is All-Knower of everything.

(260) Men whom neither trade nor sale (business) diverts from the Remembrance of Allah (with heart and tongue), nor from performing As-Salat (Iqamat-as-Salat), nor from giving the Zakat. They fear a day when hearts and eyes will be overturned (out of the horror of the torment of the day of Resurrection).
