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

(41) And thus did We show Ibrahim the kingdom of the heavens and the earth and that he might be of those who are sure.

(42) Surely I have turned myself, being upright, wholly to Him Who originated the heavens and the earth, and I am not of the polytheists.

(43) Wonderful Originator of the heavens and the earth! How could He have a son when He has no consort, and He (Himself) created everything, and He is the Knower of all things.

(44) Surely (as for) those who reject Our communications and turn away from them haughtily, the doors of heaven shall not be opened for them, nor shall they enter the garden until the camel pass through the eye of the needle; and thus do We reward the guilty.

(45) Surely your Lord is Allah, Who created the heavens and the earth in six periods of time, and He is firm in power; He throws the veil of night over the day, which it pursues incessantly; and (He created) the sun and the moon and the stars, made subservient by His command; surely His is the creation and the command; blessed is Allah, the Lord of the worlds.

(46) And if the people of the towns had believed and guarded (against evil) We would certainly have opened up for them blessings from the heaven and the earth, but they rejected, so We overtook them for what they had earned.

(47) Say: O people! surely I am the Apostle of Allah to you all, of Him Whose is the kingdom of the heavens and the earth there is no god but He; He brings to life and causes to die therefore believe in Allah and His apostle, the Ummi Prophet who believes in Allah and His words, and follow him so that you may walk in the right way.

(48) But those who were unjust among them changed it for a saying other than that which had been spoken to them; so We sent upon them a pestilence from heaven because they were unjust.

(49) Do they not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this?

(50) They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.
