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

(361) And some part of the night awake for it, a largess for thee. It may be that thy Lord will raise thee to a praised estate.

(362) And they say: We will not put faith in thee till thou cause a spring to gush forth from the earth for us;

(363) Say: If there were in the earth angels walking secure, We had sent down for them from heaven an angel as messenger.

(364) Have they not seen that Allah Who created the heavens and the earth is Able to create the like of them, and hath appointed for them an end whereof there is no doubt? But the wrong-doers refuse aught save disbelief.

(365) He said: In truth thou knowest that none sent down these (portents) save the Lord of the heavens and the earth as proofs, and lo! (for my part) I deem thee lost, O Pharaoh.

(366) And say: Praise be to Allah, Who hath not taken unto Himself a son, and Who hath no partner in the Sovereignty, nor hath He any protecting friend through dependence. And magnify Him with all magnificence.

(367) Lo! We have placed all that is on the earth as an ornament thereof that We may try them: which of them is best in conduct.

(368) And afterward We raised them up that We might know which of the two parties would best calculate the time that they had tarried.

(369) And We made firm their hearts when they stood forth and said: Our Lord is the Lord of the heavens and the earth. We cry unto no Allah beside Him, for then should we utter an enormity.

(370) And in like manner We awakened them that they might question one another. A speaker from among them said: How long have ye tarried? They said: We have tarried a day or some part of a day, (Others) said: Your Lord best knoweth what ye have tarried. Now send one of you with this your silver coin unto the city, and let him see what food is purest there and bring you a supply thereof. Let him be courteous and let no man know of you.
