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

(61) Behold! verily to Allah belong all creatures, in the heavens and on earth. What do they follow who worship as His "partners" other than Allah? They follow nothing but fancy, and they do nothing but lie.

(62) They say: "Allah hath begotten a son!" - Glory be to Him! He is self-sufficient! His are all things in the heavens and on earth! No warrant have ye for this! say ye about Allah what ye know not?

(63) Say: "Behold all that is in the heavens and on earth"; but neither Signs nor Warners profit those who believe not.

(64) He it is Who created the heavens and the earth in six Days - and His Throne was over the waters - that He might try you, which of you is best in conduct. But if thou wert to say to them, "Ye shall indeed be raised up after death", the Unbelievers would be sure to say, "This is nothing but obvious sorcery!"

(65) They will dwell therein for all the time that the heavens and the earth endure, except as thy Lord willeth: for thy Lord is the (sure) accomplisher of what He planneth.

(66) And those who are blessed shall be in the Garden: They will dwell therein for all the time that the heavens and the earth endure, except as thy Lord willeth: a gift without break.

(67) To Allah do belong the unseen (secrets) of the heavens and the earth, and to Him goeth back every affair (for decision): then worship Him, and put thy trust in Him: and thy Lord is not unmindful of aught that ye do.

(68) "O my Lord! Thou hast indeed bestowed on me some power, and taught me something of the interpretation of dreams and events,- O Thou Creator of the heavens and the earth! Thou art my Protector in this world and in the Hereafter. Take Thou my soul (at death) as one submitting to Thy will (as a Muslim), and unite me with the righteous."

(69) And how many Signs in the heavens and the earth do they pass by? Yet they turn (their faces) away from them!

(70) Allah is He Who raised the heavens without any pillars that ye can see; is firmly established on the throne (of authority); He has subjected the sun and the moon (to his Law)! Each one runs (its course) for a term appointed. He doth regulate all affairs, explaining the signs in detail, that ye may believe with certainty in the meeting with your Lord.
