The word(s) "keep" appears 94 time(s) in 90 verse(s) in Quran in Mohsin Khan translation.

(81) Allah has prepared for them a severe torment. So fear Allah and keep your duty to Him, O men of understanding who have believed! Allah has indeed sent down to you a Reminder (this Qur'an).

(82) O you who believe! Turn to Allah with sincere repentance! It may be that your Lord will expiate from you your sins, and admit you into Gardens under which rivers flow (Paradise) - the Day that Allah will not disgrace the Prophet (Muhammad صلى الله عليه وسلم) and those who believe with him. Their Light will run forward before them and (with their Records - Books of deeds) in their right hands.

(84) And whether you keep your talk secret or disclose it, Verily, He is the All-Knower of what is in the breasts (of men).

(85) And those who keep their trusts and covenants.

(86) [He (Allah) protects them (the Messengers)], till He sees that they (the Messengers) have conveyed the Messages of their Lord (Allah). And He (Allah) surrounds all that which is with them, and He (Allah) keeps count of all things (i.e. He knows the exact number of everything).

(87) And be patient (O Muhammad صلى الله عليه وسلم) with what they say, and keep away from them in a good way.

(88) And keep away from Ar-Rujz (the idols)!

(89) Over it are nineteen (angels as guardians and keepers of Hell).

(90) As for him who gives (in charity) and keeps his duty to Allah and fears Him,
