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

(121) Say: "The (Qur'an) was sent down by Him who knows the mystery (that is) in the heavens and the earth: verily He is Oft-Forgiving, Most Merciful."

(122) The Day the heaven shall be rent asunder with clouds, and angels shall be sent down, descending (in ranks),-

(123) He Who created the heavens and the earth and all that is between, in six days, and is firmly established on the Throne (of Authority): Allah Most Gracious: ask thou, then, about Him of any acquainted (with such things).

(124) Those are the ones who will be rewarded with the highest place in heaven, because of their patient constancy: therein shall they be met with salutations and peace,

(125) (Moses) said: "The Lord and Cherisher of the heavens and the earth, and all between,- if ye want to be quite sure."

(126) "(Kept them away from the Path), that they should not worship Allah, Who brings to light what is hidden in the heavens and the earth, and knows what ye hide and what ye reveal.

(127) Or, Who has created the heavens and the earth, and Who sends you down rain from the sky? Yea, with it We cause to grow well-planted orchards full of beauty of delight: it is not in your power to cause the growth of the trees in them. (Can there be another) god besides Allah? Nay, they are a people who swerve from justice.

(128) Or, Who originates creation, then repeats it, and who gives you sustenance from heaven and earth? (Can there be another) god besides Allah? Say, "Bring forth your argument, if ye are telling the truth!"

(129) Say: None in the heavens or on earth, except Allah, knows what is hidden: nor can they perceive when they shall be raised up (for Judgment).

(130) Nor is there aught of the unseen, in heaven or earth, but is (recorded) in a clear record.
