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

(311) He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement.

(312) These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones.

(313) And Allah sets forth a parable: (Consider) a town safe and secure to which its means of subsistence come in abundance from every quarter; but it became ungrateful to Allah's favors, therefore Allah made it to taste the utmost degree of hunger and fear because of what they wrought.

(314) And follow not that of which you have not the knowledge; surely the hearing and the sight and the heart, all of these, shall be questioned about that.

(315) And do not go about in the land exultingly, for you cannot cut through the earth nor reach the mountains in height.

(316) The seven heavens declare His glory and the earth (too), and those who are in them; and there is not a single thing but glorifies Him with His praise, but you do not understand their glorification; surely He is Forbearing, Forgiving.

(317) And We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.

(318) And they say: What! when we shall have become bones and decayed particles, shall we then certainly be raised up, being a new creation?

(319) And your Lord best knows those who are in the heavens and the earth; and certainly We have made some of the prophets to excel others, and to Dawood We gave a scripture.

(320) And during a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory.
