The word(s) "heaven" appears 275 time(s) in 267 verse(s) in Quran in Muhammad Habib Shakir translation.

(141) Do they not reflect within themselves: Allah did not create the heavens and the earth and what is between them two but with truth, and (for) an appointed term? And most surely most of the people are deniers of the meeting of their Lord.

(142) And to Him belongs praise in the heavens and the earth, and at nightfall and when you are at midday.

(143) And one of His signs is the creation of the heavens and the earth and the diversity of your tongues and colors; most surely there are signs in this for the learned.

(144) And one of His signs is that the heaven and the earth subsist by His command, then when He calls you with a (single) call from out of the earth, lo! you come forth.

(145) And His is whosoever is in the heavens and the earth; all are obedient to Him.

(146) And He it is Who originates the creation, then reproduces it, and it is easy to Him; and His are the most exalted attributes in the heavens and the earth, and He is the Mighty, the Wise.

(147) He created the heavens without pillars as you see them, and put mountains upon the earth lest it might convulse with you, and He spread in it animals of every kind; and We sent down water from the cloud, then caused to grow therein (vegetation) of every noble kind.

(148) O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware;

(149) Do you not see that Allah has made what is in the heavens and what is in the earth subservient to you, and made complete to you His favors outwardly and inwardly? And among men is he who disputes in respect of Allah though having no knowledge nor guidance, nor a book giving light.

(150) And if you ask them who created the heavens and the earth, they will certainly say: Allah. Say: (All) praise is due to Allah; nay! most of them do not know.
