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

(21) Those who remember Allah standing and sitting and lying on their sides and reflect on the creation of the heavens and the earth: Our Lord! Thou hast not created this in vain! Glory be to Thee; save us then from the chastisement of the fire:

(22) And whatever is in the heavens and whatever is in the earth is Allah's; and Allah encompasses all things.

(23) And whatever is in the heavens and whatever is in the earth is Allah's and certainly We enjoined those who were given the Book before you and (We enjoin) you too that you should be careful of (your duty to) Allah; and if you disbelieve, then surely whatever is in the heavens and whatever is in the earth is Allah's and Allah is Self-sufficient, Praise-worthy.

(24) And whatever is in the heavens and whatever is in the earth is Allah's, and Allah is sufficient as a Protector.

(25) The followers of the Book ask you to bring down to them a book from heaven; so indeed they demanded of Musa a greater thing than that, for they said: Show us Allah manifestly; so the lightning overtook them on account of their injustice. Then they took the calf (for a god), after clear signs had come to them, but We pardoned this; and We gave to Musa clear authority.

(26) O people! surely the Apostle has come to you with the truth from your Lord, therefore believe, (it shall be) good for you and If you disbelieve, then surely whatever is in the heavens and the earth is Allah's; and Allah is Knowing, Wise.

(27) O followers of the Book! do not exceed the limits in your religion, and do not speak (lies) against Allah, but (speak) the truth; the Messiah, Isa son of Marium is only an apostle of Allah and His Word which He communicated to Marium and a spirit from Him; believe therefore in Allah and His apostles, and say not, Three. Desist, it is better for you; Allah is only one Allah; far be It from His glory that He should have a son, whatever is in the heavens and whatever is in the earth is His, and Allah is sufficient for a Protector.

(28) Certainly they disbelieve who say: Surely, Allah-- He is the Messiah, son of Marium. Say: Who then could control anything as against Allah when He wished to destroy the Messiah son of Marium and his mother and all those on the earth? And Allah's is the kingdom of the heavens and the earth and what is between them; He creates what He pleases; and Allah has power over all things,

(29) And the Jews and the Christians say: We are the sons of Allah and His beloved ones. Say: Why does He then chastise you for your faults? Nay, you are mortals from among those whom He has created, He forgives whom He pleases and chastises whom He pleases; and Allah's is the kingdom of the heavens and the earth and what is between them, and to Him is the eventual coming.

(30) Do you not know that Allah-- His is the kingdom of the heavens and the earth; He chastises whom He pleases; and forgives whom He pleases and Allah has power over all things.
