The word(s) "art" appears 775 time(s) in 695 verse(s) in Quran in Muhammad Habib Shakir translation.

(671) And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.

(672) And the night when it departs,

(673) And he is sure that it is the (hour of) parting

(674) And during part of the night adore Him, and give glory to Him (a) long (part of the) night.

(675) Have We not made the earth to draw together to itself,

(676) Have We not made the earth an even expanse?

(677) The Lord of the heavens and the earth and what is between them, the Beneficent Allah, they shall not be able to address Him.

(678) Hearts on that day shall palpitate,

(679) And the earth, He expanded it after that.

(680) On the day that they see it, it will be as though they had not tarried but the latter part of a day or the early part of it.
