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

(101) To Him belongs what is in the heavens and on earth, and all between them, and all beneath the soil.

(102) Say: "My Lord knoweth (every) word (spoken) in the heavens and on earth: He is the One that heareth and knoweth (all things)."

(103) Not for (idle) sport did We create the heavens and the earth and all that is between!

(104) To Him belong all (creatures) in the heavens and on earth: Even those who are in His (very) Presence are not too proud to serve Him, nor are they (ever) weary (of His service):

(105) If there were, in the heavens and the earth, other gods besides Allah, there would have been confusion in both! but glory to Allah, the Lord of the Throne: (High is He) above what they attribute to Him!

(106) Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?

(107) And We have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to)!

(108) He said, "Nay, your Lord is the Lord of the heavens and the earth, He Who created them (from nothing): and I am a witness to this (Truth).

(109) The Day that We roll up the heavens like a scroll rolled up for books (completed),- even as We produced the first creation, so shall We produce a new one: a promise We have undertaken: truly shall We fulfil it.

(110) Seest thou not that to Allah bow down in worship all things that are in the heavens and on earth,- the sun, the moon, the stars; the hills, the trees, the animals; and a great number among mankind? But a great number are (also) such as are fit for Punishment: and such as Allah shall disgrace,- None can raise to honour: for Allah carries out all that He wills.
