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

(21) To Allah belongeth the dominion of the heavens and the earth; and Allah hath power over all things.

(22) Behold! in the creation of the heavens and the earth, and the alternation of night and day,- there are indeed Signs for men of understanding,-

(23) Men who celebrate the praises of Allah, standing, sitting, and lying down on their sides, and contemplate the (wonders of) creation in the heavens and the earth, (With the thought): "Our Lord! not for naught Hast Thou created (all) this! Glory to Thee! Give us salvation from the penalty of the Fire.

(24) If any do deeds of righteousness,- be they male or female - and have faith, they will enter heaven, and not the least injustice will be done to them.

(25) But to Allah belong all things in the heavens and on earth: And He it is that Encompasseth all things.

(26) To Allah belong all things in the heavens and on earth. Verily we have directed the People of the Book before you, and you (o Muslims) to fear Allah. But if ye deny Him, lo! unto Allah belong all things in the heavens and on earth, and Allah is free of all wants, worthy of all praise.

(27) Yea, unto Allah belong all things in the heavens and on earth, and enough is Allah to carry through all affairs.

(28) The people of the Book ask thee to cause a book to descend to them from heaven: Indeed they asked Moses for an even greater (miracle), for they said: "Show us Allah in public," but they were dazed for their presumption, with thunder and lightning. Yet they worshipped the calf even after clear signs had come to them; even so we forgave them; and gave Moses manifest proofs of authority.

(29) O Mankind! The Messenger hath come to you in truth from Allah: believe in him: It is best for you. But if ye reject Faith, to Allah belong all things in the heavens and on earth: And Allah is All-knowing, All-wise.

(30) O People of the Book! Commit no excesses in your religion: Nor say of Allah aught but the truth. Christ Jesus the son of Mary was (no more than) a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and His messengers. Say not "Trinity": desist: it will be better for you: for Allah is one Allah: Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs.
