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

(11) To Allah belongeth all that is in the heavens and on earth. Whether ye show what is in your minds or conceal it, Allah Calleth you to account for it. He forgiveth whom He pleaseth, and punisheth whom He pleaseth, for Allah hath power over all things.

(12) From Allah, verily nothing is hidden on earth or in the heavens.

(13) Say: "Whether ye hide what is in your hearts or reveal it, Allah knows it all: He knows what is in the heavens, and what is on earth. And Allah has power over all things.

(14) Do they seek for other than the Religion of Allah?-while all creatures in the heavens and on earth have, willing or unwilling, bowed to His Will (Accepted Islam), and to Him shall they all be brought back.

(15) To Allah belongs all that is in the heavens and on earth: To Him do all questions go back (for decision).

(16) To Allah belongeth all that is in the heavens and on earth. He forgiveth whom He pleaseth and punisheth whom He pleaseth; but Allah is Oft-Forgiving, Most Merciful.

(17) Be quick in the race for forgiveness from your Lord, and for a Garden whose width is that (of the whole) of the heavens and of the earth, prepared for the righteous,-

(18) Did ye think that ye would enter heaven without Allah testing those of you who fought hard (In His Cause) and remained steadfast?

(19) And let not those who covetously withhold of the gifts which Allah Hath given them of His Grace, think that it is good for them: Nay, it will be the worse for them: soon shall the things which they covetously withheld be tied to their necks Like a twisted collar, on the Day of Judgment. To Allah belongs the heritage of the heavens and the earth; and Allah is well-acquainted with all that ye do.

(20) They (also) said: "Allah took our promise not to believe in an messenger unless He showed us a sacrifice consumed by Fire (From heaven)." Say: "There came to you messengers before me, with clear Signs and even with what ye ask for: why then did ye slay them, if ye speak the truth?"
