The word(s) "art" appears 910 time(s) in 827 verse(s) in Quran in Muhammad Pickthal translation.

(251) And thou (Muhammad) art not occupied with any business and thou recitest not a Lecture from this (Scripture), and ye (mankind) perform no act, but We are Witness of you when ye are engaged therein. And not an atom's weight in the earth or in the sky escapeth your Lord, nor what is less than that or greater than that, but it is (written) in a clear Book.

(252) Lo! is it not unto Allah that belongeth whosoever is in the heavens and whosoever is in the earth? Those who follow aught instead of Allah follow not (His) partners. They follow only a conjecture, and they do but guess.

(253) They say: Allah hath taken (unto Him) a son - Glorified be He! He hath no needs! His is all that is in the heavens and all that is in the earth. Ye have no warrant for this. Tell ye concerning Allah that which ye know not?

(254) Recite unto them the story of Noah, when he told his people: O my people! If my sojourn (here) and my reminding you by Allah's revelations are an offence unto you, in Allah have I put my trust, so decide upon your course of action you and your partners. Let not your course of action be in doubt for you. Then have at me, give me no respite.

(255) But they denied him, so We saved him and those with him in the ship, and made them viceroys (in the earth), while We drowned those who denied Our revelations. See then the nature of the consequence for those who had been warned.

(256) Then, after him, We sent messengers unto their folk, and they brought them clear proofs. But they were not ready to believe in that which they before denied. Thus print We on the hearts of the transgressors.

(257) And Moses said: Our Lord! Lo! Thou hast given Pharaoh and his chiefs splendour and riches in the life of the world, Our Lord! that they may lead men astray from Thy way. Our Lord! Destroy their riches and harden their hearts so that they believe not till they see the painful doom.

(258) And if thou (Muhammad) art in doubt concerning that which We reveal unto thee, then question those who read the Scripture (that was) before thee. Verily the Truth from thy Lord hath come unto thee. So be not thou of the waverers.

(259) And if thy Lord willed, all who are in the earth would have believed together. Wouldst thou (Muhammad) compel men until they are believers?

(260) Say: Behold what is in the heavens and the earth! But revelations and warnings avail not folk who will not believe.
