The word(s) "heaven" appears 287 time(s) in 275 verse(s) in Quran in Mohsin Khan translation.

(111) See you not that whoever is in the heavens and whoever is on the earth, and the sun, and the moon, and the stars, and the mountains, and the trees, and Ad-Dawabb [moving (living) creatures, beasts], and many of mankind prostrate themselves to Allah. But there are many (men) on whom the punishment is justified. And whomsoever Allah disgraces, none can honour him. Verily, Allah does what He wills.

(112) To Him belongs all that is in the heavens and all that is on the earth. And verily, Allah - He is Rich (Free of all needs), Worthy of all praise.

(113) See you not that Allah has subjected to you (mankind) all that is on the earth, and the ships that sail through the sea by His Command? He withholds the heaven from falling on the earth except by His Leave. Verily, Allah is, for mankind, Full of Kindness, Most Merciful.

(114) Know you not that Allah knows all that is in the heaven and on the earth? Verily, it is (all) in the Book (Al-Lauh-al-Mahfuz). Verily that is easy for Allah.

(115) And indeed We have created above you seven heavens (one over the other), and We are never unaware of the creation.

(116) And if the truth had been in accordance with their desires, verily, the heavens and the earth, and whosoever is therein would have been corrupted! Nay, We have brought them their reminder, but they turn away from their reminder.

(117) Say: "Who is (the) Lord of the seven heavens, and (the) Lord of the Great Throne?"

(118) Allah is the Light of the heavens and the earth. The parable of His Light is as (if there were) a niche and within it a lamp: the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east (i.e. neither it gets sun-rays only in the morning) nor of the west (i.e. nor it gets sun-rays only in the afternoon, but it is exposed to the sun all day long), whose oil would almost glow forth (of itself), though no fire touched it. Light upon Light! Allah guides to His Light whom He wills. And Allah sets forth parables for mankind, and Allah is All-Knower of everything.

(119) See you not (O Muhammad صلى الله عليه وسلم) that Allah, He it is Whom glorify whosoever is in the heavens and the earth, and the birds with wings out-spread (in their flight)?. Of each one He (Allah) knows indeed his Salat (prayer) and his glorification, [or everyone knows his Salat (prayer) and his glorification]; and Allah is All-Aware of what they do.

(120) And to Allah belongs the sovereignty of the heavens and the earth, and to Allah is the return (of all).
