The word(s) "keep" appears 54 time(s) in 51 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) Those in the Fire will say to the keepers of Hell: "Pray to your Lord to lighten us the Penalty for a day (at least)!"

(42) "If ye believe me not, at least keep yourselves away from me."

(43) Almost bursting with fury: Every time a Group is cast therein, its keepers will ask, "Did no Warner come to you?"

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

(45) 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.

(46) And thy garments keep free from stain!

(47) Let any who will, keep it in remembrance!

(48) But none will keep it in remembrance except as Allah wills: He is the Lord of Righteousness, and the Lord of Forgiveness.

(49) Therefore let whoso will, keep it in remembrance.

(50) And they will not be able to keep away therefrom.
