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

(91) And Abraham! (Remember) when he said unto his folk: Serve Allah, and keep your duty unto Him; that is better for you if ye did but know.

(92) O mankind! keep your duty to your Lord and fear a Day when the parent will not be able to avail the child in aught, nor the child to avail the parent. Lo! Allah's promise is the very truth. Let not the life of the world beguile you, nor let the deceiver beguile you, in regard to Allah.

(93) O Prophet! keep thy duty to Allah and obey not the disbelievers and the hypocrites. Lo! Allah is Knower, Wise.

(94) O ye wives of the Prophet! Ye are not like any other women. If ye keep your duty (to Allah), then be not soft of speech, lest he in whose heart is a disease aspire (to you), but utter customary speech.

(95) And when thou saidst unto him on whom Allah hath conferred favour and thou hast conferred favour: keep thy wife to thyself, and fear Allah. And thou didst hide in thy mind that which Allah was to bring to light, and thou didst fear mankind whereas Allah hath a better right that thou shouldst fear Him. So when Zeyd had performed that necessary formality (of divorce) from her, We gave her unto thee in marriage, so that (henceforth) there may be no sin for believers in respect of wives of their adopted sons, when the latter have performed the necessary formality (of release) from them. The commandment of Allah must be fulfilled.

(96) Who delivered the messages of Allah and feared Him, and feared none save Allah. Allah keepeth good account.

(97) Whether ye divulge a thing or keep it hidden, lo! Allah is ever Knower of all things.

(98) It is no sin for them (thy wives) to converse freely) with their fathers, or their sons, or their brothers, or their brothers' sons, or the sons of their sisters or of their own women, or their slaves. O women! keep your duty to Allah. Lo! Allah is ever Witness over all things.

(99) But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not His promise.

(100) Allah receiveth (men's) souls at the time of their death, and that (soul) which dieth not (yet) in its sleep. He keepeth that (soul) for which He hath ordained death and dismisseth the rest till an appointed term. Lo! herein verily are portents for people who take thought.
