The word(s) "night" appears 144 time(s) in 113 verse(s) in Quran in Mohsin Khan translation.

(11) They may hide (their crimes) from men, but they cannot hide (them) from Allah; for He is with them (by His Knowledge), when they plot by night in words that He does not approve. And Allah ever encompasses what they do.

(12) And to Him belongs whatsoever exists in the night and the day, and He is the All-Hearing, the All-Knowing."

(13) Say: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?"

(14) It is He Who takes your souls by night (when you are asleep), and has knowledge of all that you have done by day, then He raises (wakes) you up again that a term appointed (your life period) be fulfilled, then (in the end) unto Him will be your return. Then He will inform you of that which you used to do.

(15) When the night covered him over with darkness he saw a star. He said: "This is my lord." But when it set, he said: "I like not those that set."

(16) (He is the) Cleaver of the daybreak. He has appointed the night for resting, and the sun and the moon for reckoning. Such is the measuring of the All-Mighty, the All-Knowing.

(17) And a great number of towns (their population) We destroyed (for their crimes). Our torment came upon them (suddenly) by night or while they were taking their midday nap.

(18) Indeed your Lord is Allah, Who created the heavens and the earth in Six Days, and then He rose over (Istawa) the Throne (really in a manner that suits His Majesty). He brings the night as a cover over the day, seeking it rapidly, and (He created) the sun, the moon, the stars subjected to His Command. Surely, His is the Creation and Commandment. Blessed is Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)!

(19) Did the people of the towns then feel secure against the coming of Our punishment by night while they were asleep?

(20) And We appointed for Musa (Moses) thirty nights and added (to the period) ten (more), and he completed the term, appointed by his Lord, of forty nights. And Musa (Moses) said to his brother Harun (Aaron): "Replace me among my people, act in the Right Way (by ordering the people to obey Allah and to worship Him Alone) and follow not the way of the Mufsidun (mischief-makers)."
