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

(41) Await they aught save the hour, that it shall come upon them suddenly, when they know not?

(42) And blessed be He unto Whom belongeth the Sovereignty of the heavens and the earth and all that is between them, and with Whom is knowledge of the hour, and unto Whom ye will be returned.

(43) And unto Allah belongeth the Sovereignty of the heavens and the earth; and on the day when the hour riseth, on that day those who follow falsehood will be lost.

(44) And when it was said: Lo! Allah's promise is the truth, and there is no doubt of the hour's coming, ye said: We know not what the hour is. We deem it naught but a conjecture, and we are by no means convinced.

(45) Then have patience (O Muhammad) even as the stout of heart among the messengers (of old) had patience, and seek not to hasten on (the doom) for them. On the day when they see that which they are promised (it will seem to them) as though they had tarried but an hour of daylight. A clear message. Shall any be destroyed save evil-living folk?

(46) Await they aught save the hour, that it should come upon them unawares? And the beginnings thereof have already come. But how, when it hath come upon them, can they take their warning?

(47) The threatened hour is nigh.

(48) The hour drew nigh and the moon was rent in twain.

(49) Nay, but the hour (of doom) is their appointed tryst, and the hour will be more wretched and more bitter (than their earthly failure).

(50) They ask thee of the hour: when will it come to port?
