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

(101) And those who keep their duty to their Lord are driven unto the Garden in troops till, when they reach it, and the gates thereof are opened, and the warders thereof say unto them: Peace be unto you! Ye are good, so enter ye (the Garden of delight), to dwell therein;

(102) And We delivered those who believed and used to keep their duty to Allah.

(103) If He will He calmeth the wind so that they keep still upon its surface - Lo! herein verily are signs for every steadfast grateful (heart). -

(104) And ornaments of gold. Yet all that would have been but a provision of the life of the world. And the Hereafter with your Lord would have been for those who keep from evil.

(105) When Jesus came with clear proofs (of Allah's Sovereignty), he said: I have come unto you with wisdom, and to make plain some of that concerning which ye differ. So keep your duty to Allah, and obey me.

(106) A similitude of the Garden which those who keep their duty (to Allah) are promised: Therein are rivers of water unpolluted, and rivers of milk whereof the flavour changeth not, and rivers of wine delicious to the drinkers, and rivers of clear-run honey; therein for them is every kind of fruit, with pardon from their Lord. (Are those who enjoy all this) like those who are immortal in the Fire and are given boiling water to drink so that it teareth their bowels?

(107) Lo! those who swear allegiance unto thee (Muhammad), swear allegiance only unto Allah. The Hand of Allah is above their hands. So whosoever breaketh his oath, breaketh it only to his soul's hurt; while whosoever keepeth his covenant with Allah, on him will He bestow immense reward.

(108) O ye who believe! Be not forward in the presence of Allah and His messenger, and keep your duty to Allah. Lo! Allah is Hearer, Knower.

(109) O ye who believe! Shun much suspicion; for lo! some suspicion is a crime. And spy not, neither backbite one another. Would one of you love to eat the flesh of his dead brother? Ye abhor that (so abhor the other)! And keep your duty (to Allah). Lo! Allah is Relenting, Merciful.

(110) Lo! those who keep from evil will dwell amid gardens and watersprings,
