The word(s) "heaven" appears 275 time(s) in 267 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) Say: Who is the Lord of the heavens and the earth?-- Say: Allah. Say: Do you take then besides Him guardians who do not control any profit or harm for themselves? Say: Are the blind and the seeing alike? Or can the darkness and the light be equal? Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme.

(72) (Of) Allah, Whose is whatever is in the heavens and whatever Is in the earth; and woe to the unbelievers on account of the severe chastisement,

(73) Their apostles said: Is there doubt about Allah, the Maker of the heavens and the earth? He invites you to forgive you your faults and to respite you till an appointed term. They said: You are nothing but mortals like us; you wish to turn us away from what our fathers used to worship; bring us therefore some clear authority.

(74) Do you not see that Allah created the heavens and the earth with truth? If He please He will take you off and bring a new creation,

(75) Have you not considered how Allah sets forth a parable of a good word (being) like a good tree, whose root is firm and whose branches are in heaven,

(76) Allah is He Who created the heavens and the earth and sent down water from the clouds, then brought forth with it fruits as a sustenance for you, and He has made the ships subservient to you, that they might run their course in the sea by His command, and He has made the rivers subservient to you.

(77) O our Lord! Surely Thou knowest what we hide and what we make public, and nothing in the earth nor any thing in heaven is hidden from Allah:

(78) On the day when the earth shall be changed into a different earth, and the heavens (as well), and they shall come forth before Allah, the One, the Supreme.

(79) And even if We open to them a gateway of heaven, so that they ascend into it all the while,

(80) And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders.
