The word(s) "keep" appears 114 time(s) in 108 verse(s) in Quran in Muhammad Habib Shakir translation.

(101) Almost bursting for fury. Whenever a group is cast into it, its keeper shall ask them: Did there not come to you a warner?

(102) And those who keep a guard on their prayer,

(103) And that if they should keep to the (right) way, We would certainly give them to drink of abundant water,

(104) Surely your Lord knows that you pass in prayer nearly two-thirds of the night, and (sometimes) half of it, and (sometimes) a third of it, and (also) a party of those with you; and Allah measures the night and the day. He knows that you are not able to do it, so He has turned to you (mercifully), therefore read what is easy of the Quran. He knows that there must be among you sick, and others who travel in the land seeking of the bounty of Allah, and others who fight in Allah's way, therefore read as much of it as is easy (to you), and keep up prayer and pay the poor-rate and offer to Allah a goodly gift, and whatever of good you send on beforehand for yourselves, you will find it with Allah; that is best and greatest in reward; and ask forgiveness of Allah; surely Allah is Forgiving, Merciful.

(105) And most surely there are keepers over you

(106) And they were not sent to be keepers over them.

(107) There is not a soul but over it is a keeper.

(108) And they were not enjoined anything except that they should serve Allah, being sincere to Him in obedience, upright, and keep up prayer and pay the poor-rate, and that is the right religion.
