The word(s) "hour" appears 56 time(s) in 51 verse(s) in Quran in Muhammad Pickthal translation.

(1) He said: My Lord! Appoint a token for me. (The angel) said: The token unto thee (shall be) that thou shalt not speak unto mankind three days except by signs. Remember thy Lord much, and praise (Him) in the early hours of night and morning.

(2) They indeed are losers who deny their meeting with Allah until, when the hour cometh on them suddenly, they cry: Alas for us, that we neglected it! They bear upon their backs their burdens. Ah, evil is that which they bear!

(3) Say: Can ye see yourselves, if the punishment of Allah come upon you or the hour come upon you, (calling upon other than Allah)? Do ye then call (for help) to any other than Allah? (Answer that) if ye are truthful.

(4) And every nation hath its term, and when its term cometh, they cannot put it off an hour nor yet advance (it).

(5) They ask thee of the (destined) hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not.

(6) Allah hath turned in mercy to the Prophet, and to the Muhajirin and the Ansar who followed him in the hour of hardship. After the hearts of a party of them had almost swerved aside, then turned He unto them in mercy. Lo! He is Full of Pity, Merciful for them.

(7) And on the day when He shall gather them together, (when it will seem) as though they had tarried but an hour of the day, recognising one another, those will verily have perished who denied the meeting with Allah and were not guided.

(8) Say: I have no power to hurt or benefit myself, save that which Allah willeth. For every nation there is an appointed time. When their time cometh, then they cannot put it off an hour, nor hasten (it).

(9) Deem they themselves secure from the coming on them of a pall of Allah's punishment, or the coming of the hour suddenly while they are unaware?

(10) And unto Allah falleth prostrate whosoever is in the heavens and the earth, willingly or unwillingly, as do their shadows in the morning and the evening hours.
