The word(s) "hour" appears 77 time(s) in 63 verse(s) in Quran in Mohsin Khan translation.

(41) The Fire, they are exposed to it, morning and afternoon. And on the Day when the hour will be established (it will be said to the angels): "Cause Fir'aun's (Pharaoh) people to enter the severest torment!"

(42) Verily, the hour (Day of Judgement) is surely coming, there is no doubt about it, yet most men believe not.

(43) To Him (Alone) is referred the knowledge of the hour. No fruit comes out of its sheath, nor does a female conceive nor brings forth (young), except by His Knowledge. And on the Day when He will call unto them (polytheists) (saying): "Where are My (so-called) partners (whom you did invent)?" They will say: "We inform You that none of us bears witness to it (that they are Your partners)!"

(44) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(45) It is Allah Who has sent down the Book (the Qur'an) in truth, and the Balance (i.e. to act justly). And what can make you know that perhaps the hour is close at hand?

(46) Those who believe not therein seek to hasten it, while those who believe are fearful of it, and know that it is the very truth. Verily, those who dispute concerning the hour are certainly in error far away.

(47) And he ['Îsa (Jesus), son of Maryam (Mary)] shall be a known sign for (the coming of) the hour (Day of Resurrection) [i.e. 'Isa's (Jesus) descent on the earth]. Therefore have no doubt concerning it (i.e. the Day of Resurrection). And follow Me (Allah) (i.e. be obedient to Allah and do what He orders you to do, O mankind)! This is the Straight Path (of Islamic Monotheism, leading to Allah and to His Paradise).

(48) Do they only wait for the hour that it shall come upon them suddenly, while they perceive not?

(49) And Blessed be He to Whom belongs the kingdom of the heavens and the earth, and all that is between them, and with Whom is the knowledge of the hour, and to Whom you (all) will be returned.

(50) And to Allah belongs the kingdom of the heavens and the earth. And on the Day that the hour will be established - on that Day the followers of falsehood (polytheists, disbelievers, worshippers of false deities) shall lose (everything).
