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

(51) And when they said: O Allah! if this is the truth from Thee, then rain upon us stones from heaven or inflict on us a painful punishment.

(52) Surely the number of months with Allah is twelve months in Allah's ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right reckoning; therefore be not unjust to yourselves regarding them, and fight the polytheists all together as they fight you all together; and know that Allah is with those who guard (against evil).

(53) Surely Allah's is the kingdom of the heavens and the earth; He brings to life and causes to die; and there is not for you besides Allah any Guardian or Helper.

(54) Surely your Lord is Allah, Who created the heavens and the earth in six periods, and He is firm in power, regulating the affair, there is no intercessor except after His permission; this is Allah, your Lord, therefore serve Him; will you not then mind?

(55) Most surely in the variation of the night and the day, and what Allah has created in the heavens and the earth, there are signs for a people who guard (against evil).

(56) And they serve beside Allah what can neither harm them nor profit them, and they say: These are our intercessors with Allah. Say: Do you (presume to) inform Allah of what He knows not in the heavens and the earth? Glory be to Him, and supremely exalted is He above what they set up (with Him).

(57) Say: Who gives you sustenance from the heaven and the earth? Or Who controls the hearing and the sight? And Who brings forth the living from the dead, and brings forth the dead from the living? And Who regulates the affairs? Then they will say: Allah. Say then: Will you not then guard (against evil)?

(58) Now surely Allah's is what is in the heavens and the earth; now surely Allah's promise is true, but most of them do not know.

(59) And you are not (engaged) in any affair, nor do you recite concerning it any portion of the Quran, nor do you do any work but We are witnesses over you when you enter into it, and there does not lie concealed from your Lord the weight of an atom in the earth or in the heaven, nor any thing less than that nor greater, but it is in a clear book.

(60) Now, surely, whatever is in the heavens and whatever is in the earth is Allah's; and they do not (really) follow any associates, who call on others besides Allah; they do not follow (anything) but conjectures, and they only lie.
