The word(s) "art" appears 982 time(s) in 870 verse(s) in Quran in Abdullah Yusuf Ali translation.

(831) But keep in remembrance the name of thy Lord and devote thyself to Him whole-heartedly.

(832) One Day the earth and the mountains will be in violent commotion. And the mountains will be as a heap of sand poured out and flowing down.

(833) Thy Lord doth know that thou standest forth (to prayer) nigh two-thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill-health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, therefore, as much of the Qur'an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah a Beautiful Loan. And whatever good ye send forth for your souls ye shall find it in Allah's Presence,- yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft-Forgiving, Most Merciful.

(834) And We have set none but angels as Guardians of the Fire; and We have fixed their number only as a trial for Unbelievers,- in order that the People of the Book may arrive at certainty, and the Believers may increase in Faith,- and that no doubts may be left for the People of the Book and the Believers, and that those in whose hearts is a disease and the Unbelievers may say, "What symbol doth Allah intend by this?" Thus doth Allah leave to stray whom He pleaseth, and guide whom He pleaseth: and none can know the forces of thy Lord, except He and this is no other than a warning to mankind.

(835) And he will conclude that it was (the Time) of Parting;

(836) And part of the night, prostrate thyself to Him; and glorify Him a long night through.

(837) Have We not made the earth (as a place) to draw together.

(838) (It will be said:) "Depart ye to that which ye used to reject as false!

(839) "Depart ye to a Shadow (of smoke ascending) in three columns,

(840) "Eat ye and drink ye to your heart's content: for that ye worked (Righteousness).
