The word(s) "heaven" appears 287 time(s) in 275 verse(s) in Quran in Mohsin Khan translation.

(241) And what is the matter with you that you spend not in the Cause of Allah? And to Allah belongs the heritage of the heavens and the earth. Not equal among you are those who spent and fought before the conquering (of Makkah, with those among you who did so later). Such are higher in degree than those who spent and fought afterwards. But to all Allah has promised the best (reward). And Allah is All-Aware of what you do.

(242) Race with one another in hastening towards forgiveness from your Lord (Allah), and Paradise the width whereof is as the width of the heaven and the earth, prepared for those who believe in Allah and His Messengers. That is the Grace of Allah which He bestows on whom He is pleased with. And Allah is the Owner of Great Bounty.

(243) Have you not seen that Allah knows whatsoever is in the heavens and whatsoever is on the earth? There is no Najwa (secret counsel) of three but He is their fourth (with His Knowledge, while He Himself is over the Throne, over the seventh heaven), nor of five but He is their sixth (with His Knowledge), nor of less than that or more but He is with them (with His Knowledge) wheresoever they may be. And afterwards on the Day of Resurrection He will inform them of what they did. Verily, Allah is the All-Knower of everything.

(244) Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. And He is the All-Mighty, the All-Wise.

(245) He is Allah, the Creator, the Inventor of all things, the Bestower of forms. To Him belong the Best Names. All that is in the heavens and the earth glorify Him. And He is the All-Mighty, the All-Wise.

(246) Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. And He is the All-Mighty, the All-Wise.

(247) Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah, the King (of everything), the Holy, the All-Mighty, the All-Wise.

(248) They are the ones who say: "Spend not on those who are with Allah's Messenger, until they desert him." And to Allah belong the treasures of the heavens and the earth, but the hypocrites comprehend not.

(249) Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. His is the dominion, and to Him belong all the praises and thanks, and He is Able to do all things.

(250) He has created the heavens and the earth with truth, and He shaped you and made good your shapes. And to Him is the final Return.
