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

(21) O mankind! Fear your Lord. Lo! the earthquake of the hour (of Doom) is a tremendous thing.

(22) And because the hour will come, there is no doubt thereof; and because Allah will raise those who are in the graves.

(23) And those who disbelieve will not cease to be in doubt thereof until the hour come upon them unawares, or there come unto them the doom of a disastrous day.

(24) Nay, but they deny (the coming of) the hour, and for those who deny (the coming of) the hour We have prepared a flame.

(25) He verily led me astray from the Reminder after it had reached me. Satan was ever man's deserter in the hour of need.

(26) And in the day when the hour riseth the unrighteous will despair.

(27) In the day when the hour cometh, in that day they will be sundered.

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

(29) Lo! Allah! With Him is knowledge of the hour. He sendeth down the rain, and knoweth that which is in the wombs. No soul knoweth what it will earn to-morrow, and no soul knoweth in what land it will die. Lo! Allah is Knower, Aware.

(30) Men ask thee of the hour. Say: The knowledge of it is with Allah only. What can convey (the knowledge) unto thee? It may be that the hour is nigh.
