The word(s) "heaven" appears 249 time(s) in 244 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) Even if We opened out to them a gate from heaven, and they were to continue (all day) ascending therein,

(82) It is We Who have set out the zodiacal signs in the heavens, and made them fair-seeming to (all) beholders;

(83) We created not the heavens, the earth, and all between them, but for just ends. And the Hour is surely coming (when this will be manifest). So overlook (any human faults) with gracious forgiveness.

(84) He has created the heavens and the earth for just ends: Far is He above having the partners they ascribe to Him!

(85) And to Allah doth obeisance all that is in the heavens and on earth, whether moving (living) creatures or the angels: for none are arrogant (before their Lord).

(86) To Him belongs whatever is in the heavens and on earth, and to Him is duty due always: then will ye fear other than Allah?

(87) And worship others than Allah,- such as have no power of providing them, for sustenance, with anything in heavens or earth, and cannot possibly have such power?

(88) To Allah belongeth the Mystery of the heavens and the earth. And the Decision of the Hour (of Judgment) is as the twingkling of an eye, or even quicker: for Allah hath power over all things.

(89) The seven heavens and the earth, and all beings therein, declare His glory: there is not a thing but celebrates His praise; And yet ye understand not how they declare His glory! Verily He is Oft-Forbear, Most Forgiving!

(90) And it is your Lord that knoweth best all beings that are in the heavens and on earth: We did bestow on some prophets more (and other) gifts than on others: and We gave to David (the gift of) the Psalms.
