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

(81) And We did not create the heavens and the earth and what is between them two but in truth; and the hour is most surely coming, so turn away with kindly forgiveness.

(82) He created the heavens and the earth with the truth, highly exalted be He above what they associate (with Him).

(83) And whatever creature that is in the heavens and that is in the earth makes obeisance to Allah (only), and the angels (too) and they do not show pride.

(84) And whatever is in the heavens and the earth is His, and to Him should obedience be (rendered) constantly; will you then guard against other than (the punishment of) Allah?

(85) And they serve besides Allah that which does not control for them any sustenance at all from the heavens and the earth, nor have they any power.

(86) And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has power over all things.

(87) The seven heavens declare His glory and the earth (too), and those who are in them; and there is not a single thing but glorifies Him with His praise, but you do not understand their glorification; surely He is Forbearing, Forgiving.

(88) And your Lord best knows those who are in the heavens and the earth; and certainly We have made some of the prophets to excel others, and to Dawood We gave a scripture.

(89) Or you should cause the heaven to come down upon us in pieces as you think, or bring Allah and the angels face to face (with us).

(90) Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle?
