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

(211) Or did they create the heavens and the earth? Nay, they have no firm belief.

(212) Or have they a ladder, by which they can (climb up to heaven and) listen (to its secrets)? Then let (such a) listener of theirs produce a manifest proof.

(213) How many-so-ever be the angels in the heavens, their intercession will avail nothing except after Allah has given leave for whom He pleases and that he is acceptable to Him.

(214) Yea, to Allah belongs all that is in the heavens and on earth: so that He rewards those who do evil, according to their deeds, and He rewards those who do good, with what is best.

(215) So We opened the gates of heaven, with water pouring forth.

(216) Of Him seeks (its need) every creature in the heavens and on earth: every day in (new) Splendour doth He (shine)!

(217) O ye assembly of Jinns and men! If it be ye can pass beyond the zones of the heavens and the earth, pass ye! not without authority shall ye be able to pass!

(218) Whatever is in the heavens and on earth,- let it declare the Praises and Glory of Allah: for He is the Exalted in Might, the Wise.

(219) To Him belongs the dominion of the heavens and the earth: It is He Who gives Life and Death; and He has Power over all things.

(220) He it is Who created the heavens and the earth in Six Days, and is moreover firmly established on the Throne (of Authority). He knows what enters within the earth and what comes forth out of it, what comes down from heaven and what mounts up to it. And He is with you wheresoever ye may be. And Allah sees well all that ye do.
