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

(151) He rules (all) affairs from the heavens to the earth: in the end will (all affairs) go up to Him, on a Day, the space whereof will be (as) a thousand years of your reckoning.

(152) We did indeed offer the Trust to the heavens and the Earth and the Mountains; but they refused to undertake it, being afraid thereof: but man undertook it;- He was indeed unjust and foolish;-

(153) Praise be to Allah, to Whom belong all things in the heavens and on earth: to Him be Praise in the Hereafter: and He is Full of Wisdom, acquainted with all things.

(154) The Unbelievers say, "Never to us will come the Hour": Say, "Nay! but most surely, by my Lord, it will come upon you;- by Him Who knows the unseen,- from Whom is not hidden the least little atom in the heavens or on earth: Nor is there anything less than that, or greater, but is in the Record Perspicuous:

(155) Say: "Call upon other (gods) whom ye fancy, besides Allah: They have no power,- not the weight of an atom,- in the heavens or on earth: No (sort of) share have they therein, nor is any of them a helper to Allah.

(156) Say: "Who gives you sustenance, from the heavens and the earth?" Say: "It is Allah; and certain it is that either we or ye are on right guidance or in manifest error!"

(157) Praise be to Allah, Who created (out of nothing) the heavens and the earth, Who made the angels, messengers with wings,- two, or three, or four (pairs): He adds to Creation as He pleases: for Allah has power over all things.

(158) O men! Call to mind the grace of Allah unto you! is there a creator, other than Allah, to give you sustenance from heaven or earth? There is no god but He: how then are ye deluded away from the Truth?

(159) Verily Allah knows (all) the hidden things of the heavens and the earth: verily He has full knowledge of all that is in (men's) hearts.

(160) Say: "Have ye seen (these) 'Partners' of yours whom ye call upon besides Allah? Show Me what it is they have created in the (wide) earth. Or have they a share in the heavens? Or have We given them a Book from which they (can derive) clear (evidence)?- Nay, the wrong-doers promise each other nothing but delusions.
