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

(71) Say (O Muhammad صلى الله عليه و سلم): "Who is the Lord of the heavens and the earth?" Say: "(It is) Allah." Say: "Have you then taken (for worship) Auliya' (protectors) other than Him, such as have no power either for benefit or for harm to themselves?" Say: "Is the blind equal to the one who sees? Or darkness equal to light? Or do they assign to Allah partners who created the like of His creation, so that the creation (which they made and His creation) seemed alike to them?" Say: "Allah is the Creator of all things; and He is the One, the Irresistible."

(72) Allah to Whom belongs all that is in the heavens and all that is in the earth! And woe unto the disbelievers from a severe torment.

(73) Their Messengers said: "What! Can there be a doubt about Allah, the Creator of the heavens and the earth? He calls you (to Monotheism and to be obedient to Allah) that He may forgive you of your sins and give you respite for a term appointed." They said: "You are no more than human beings like us! You wish to turn us away from what our fathers used to worship. Then bring us a clear authority (i.e. a clear proof of what you say)."

(74) Do you not see that Allah has created the heavens and the earth with truth? If He wills, He can remove you and bring (in your place) a new creation!

(75) Allah is He Who has created the heavens and the earth and sends down water (rain) from the sky, and thereby brought forth fruits as provision for you; and He has made the ships to be of service to you, that they may sail through the sea by His Command; and He has made rivers (also) to be of service to you.

(76) "O our Lord! Certainly, You know what we conceal and what we reveal. Nothing on the earth or in the heaven is hidden from Allah.

(77) On the Day when the earth will be changed to another earth and so will be the heavens, and they (all creatures) will appear before Allah, the One, the Irresistible.

(78) And even if We opened to them a gate from the heaven and they were to keep on ascending thereto (all the day long)

(79) They would surely say (in the evening): "Our eyes have been (as if) dazzled (we have not seen any angel or heaven). Nay, we are a people bewitched."

(80) And indeed, We have put the big stars in the heaven and We beautified it for the beholders.
