The word(s) "night" appears 113 time(s) in 97 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) See they not that We have made the night for them to rest in and the Day to give them light? Verily in this are Signs for any people that believe!

(52) Say: See ye? If Allah were to make the night perpetual over you to the Day of Judgment, what god is there other than Allah, who can give you enlightenment? Will ye not then hearken?

(53) Say: See ye? If Allah were to make the day perpetual over you to the Day of Judgment, what god is there other than Allah, who can give you a night in which ye can rest? Will ye not then see?

(54) It is out of His Mercy that He has made for you night and Day,- that ye may rest therein, and that ye may seek of his Grace;- and in order that ye may be grateful.

(55) And among His Signs is the sleep that ye take by night and by day, and the quest that ye (make for livelihood) out of His Bounty: verily in that are signs for those who hearken.

(56) Seest thou not that Allah merges night into Day and he merges Day into night; that He has subjected the sun, and the moon (to his Law), each running its course for a term appointed; and that Allah is well-acquainted with all that ye do?

(57) Between them and the Cities on which We had poured our blessings, We had placed Cities in prominent positions, and between them We had appointed stages of journey in due proportion: "Travel therein, secure, by night and by day."

(58) Those who had been despised will say to the arrogant ones: "Nay! it was a plot (of yours) by day and by night: Behold! Ye (constantly) ordered us to be ungrateful to Allah and to attribute equals to Him!" They will declare (their) repentance when they see the Penalty: We shall put yokes on the necks of the Unbelievers: It would only be a requital for their (ill) Deeds.

(59) He merges night into Day, and he merges Day into night, and he has subjected the sun and the moon (to his Law): each one runs its course for a term appointed. Such is Allah your Lord: to Him belongs all Dominion. And those whom ye invoke besides Him have not the least power.

(60) And a Sign for them is the night: We withdraw therefrom the Day, and behold they are plunged in darkness;
