The word(s) "rest" appears 115 time(s) in 115 verse(s) in Quran in Abdullah Yusuf Ali translation.

(91) But to those who receive Guidance, He increases the (light of) Guidance, and bestows on them their Piety and restraint (from evil).

(92) Allah has promised you many gains that ye shall acquire, and He has given you these beforehand; and He has restrained the hands of men from you; that it may be a Sign for the Believers, and that He may guide you to a Straight Path;

(93) And it is He Who has restrained their hands from you and your hands from them in the midst of Makka, after that He gave you the victory over them. And Allah sees well all that ye do.

(94) While the Unbelievers got up in their hearts heat and cant - the heat and cant of ignorance,- Allah sent down His Tranquillity to his Messenger and to the Believers, and made them stick close to the command of self-restraint; and well were they entitled to it and worthy of it. And Allah has full knowledge of all things.

(95) In them will be (Maidens), chaste, restraining their glances, whom no man or Jinn before them has touched;-

(96) Companions restrained (as to their glances), in (goodly) pavilions;-

(97) These will be those Nearest to Allah:

(98) Thus, then, if he be of those Nearest to Allah,

(99) (There is for him) rest and Satisfaction, and a Garden of Delights.

(100) O ye who believe! When ye hold secret counsel, do it not for iniquity and hostility, and disobedience to the Prophet; but do it for righteousness and self-restraint; and fear Allah, to Whom ye shall be brought back.
