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

(91) Say: "If there were on the earth, angels walking about in peace and security, We should certainly have sent down for them from the heaven an angel as a Messenger."

(92) See they not that Allah, Who created the heavens and the earth, is Able to create the like of them. And He has decreed for them an appointed term, whereof there is no doubt. But the Zalimun (polytheists and wrong-doers) refuse (the truth - the Message of Islamic Monotheism, and accept nothing) but disbelief.

(93) [Musa (Moses)] said: "Verily, you know that these signs have been sent down by none but the Lord of the heavens and the earth (as clear evidence i.e. proofs of Allah's Oneness and His Omnipotence.). And I think you are, indeed, O Fir'aun (Pharaoh) doomed to destruction (away from all good)!"

(94) And We made their hearts firm and strong (with the light of Faith in Allah and bestowed upon them patience to bear the separation of their kith and kin and dwellings) when they stood up and said: "Our Lord is the Lord of the heavens and the earth, never shall we call upon any ilah (god) other than Him; if we did, we should indeed have uttered an enormity in disbelief.

(95) Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the Unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector) other than Him, and He makes none to share in His Decision and His Rule."

(96) I (Allah) made them (Iblis and his offspring) not to witness (nor took their help in) the creation of the heavens and the earth and not (even) their own creation, nor was I (Allah) to take the misleaders as helpers.

(97) Lord of the heavens and the earth, and all that is between them, so worship Him (Alone) and be constant and patient in His worship. Do you know of any who is similar to Him? (of course none is similar or co-equal or comparable to Him, and He has none as partner with Him). [There is nothing like Him and He is the All-Hearer, the All-Seer].

(98) Whereby the heavens are almost torn, and the earth is split asunder, and the mountains fall in ruins,

(99) There is none in the heavens and the earth but comes unto the Most Gracious (Allah) as a slave.

(100) A revelation from Him (Allah) Who has created the earth and high heavens.
