The word(s) "keep" appears 132 time(s) in 129 verse(s) in Quran in Muhammad Pickthal translation.

(121) And keep your opinion secret or proclaim it, lo! He is Knower of all that is in the breasts (of men).

(122) Lo! for those who keep from evil are gardens of bliss with their Lord.

(123) And those who keep their pledges and their covenant,

(124) What aileth those who disbelieve, that they keep staring toward thee (O Muhammad), open-eyed,

(125) (Bidding you): Serve Allah and keep your duty unto Him and obey me,

(126) That He may know that they have indeed conveyed the messages of their Lord. He surroundeth all their doings, and He keepeth count of all things.

(127) keep vigil the night long, save a little -

(128) Lo! thy Lord knoweth how thou keepest vigil sometimes nearly two-thirds of the night, or (sometimes) half or a third thereof, as do a party of those with thee. Allah measureth the night and the day. He knoweth that ye count it not, and turneth unto you in mercy. Recite, then, of the Qur'an that which is easy for you. He knoweth that there are sick folk among you, while others travel in the land in search of Allah's bounty, and others (still) are fighting for the cause of Allah. So recite of it that which is easy (for you), and establish worship and pay the poor-due, and (so) lend unto Allah a goodly loan. Whatsoever good ye send before you for your souls, ye will find it with Allah, better and greater in the recompense. And seek forgiveness of Allah. Lo! Allah is Forgiving, Merciful.

(129) And they are ordered naught else than to serve Allah, keeping religion pure for Him, as men by nature upright, and to establish worship and to pay the poor-due. That is true religion.
