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

(141) And among His Signs is this, that heaven and earth stand by His Command: then when He calls you, by a single call, from the earth, behold, ye (straightway) come forth.

(142) To Him belongs every being that is in the heavens and on earth: all are devoutly obedient to Him.

(143) It is He Who begins (the process of) creation; then repeats it; and for Him it is most easy. To Him belongs the loftiest similitude (we can think of) in the heavens and the earth: for He is Exalted in Might, full of wisdom.

(144) Those who reject Faith will suffer from that rejection: and those who work righteousness will spread their couch (of repose) for themselves (in heaven):

(145) He created the heavens without any pillars that ye can see; He set on the earth mountains standing firm, lest it should shake with you; and He scattered through it beasts of all kinds. We send down rain from the sky, and produce on the earth every kind of noble creature, in pairs.

(146) "O my son!" (said Luqman), "If there be (but) the weight of a mustard-seed and it were (hidden) in a rock, or (anywhere) in the heavens or on earth, Allah will bring it forth: for Allah understands the finest mysteries, (and) is well-acquainted (with them).

(147) Do ye not see that Allah has subjected to your (use) all things in the heavens and on earth, and has made his bounties flow to you in exceeding measure, (both) seen and unseen? Yet there are among men those who dispute about Allah, without knowledge and without guidance, and without a Book to enlighten them!

(148) If thou ask them, who it is that created the heavens and the earth. They will certainly say, "Allah". Say: "Praise be to Allah!" But most of them understand not.

(149) To Allah belong all things in heaven and earth: verily Allah is He (that is) free of all wants, worthy of all praise.

(150) It is Allah Who has created the heavens and the earth, and all between them, in six Days, and is firmly established on the Throne (of Authority): ye have none, besides Him, to protect or intercede (for you): will ye not then receive admonition?
