The word(s) "rest" appears 68 time(s) in 67 verse(s) in Quran in Muhammad Pickthal translation.

(41) Those who have earned the Garden on that day will be better in their home and happier in their place of noonday rest;

(42) Have they not seen how We have appointed the night that they may rest therein, and the day sight-giving? Lo! therein verily are portents for a people who believe.

(43) And We inspired the mother of Moses, saying: Suckle him and, when thou fearest for him, then cast him into the river and fear not nor grieve. Lo! We shall bring him back unto thee and shall make him (one) of Our messengers.

(44) So We restored him to his mother that she might be comforted and not grieve, and that she might know that the promise of Allah is true. But most of them know not.

(45) He said: Lo! I fain would marry thee to one of these two daughters of mine on condition that thou hirest thyself to me for (the term of) eight pilgrimages. Then if thou completest ten it will be of thine own accord, for I would not make it hard for thee. Allah willing, thou wilt find me of the righteous.

(46) Say: Have ye thought, if Allah made day everlasting for you till the Day of Resurrection, who is a god beside Allah who could bring you night wherein ye rest? Will ye not then see?

(47) Of His mercy hath He appointed for you night and day, that therein ye may rest, and that ye may seek His bounty, and that haply ye may be thankful.

(48) And of His signs is this: He created for you helpmeets from yourselves that ye might find rest in them, and He ordained between you love and mercy. Lo! herein indeed are portents for folk who reflect.

(49) O Prophet! Lo! We have made lawful unto thee thy wives unto whom thou hast paid their dowries, and those whom thy right hand possesseth of those whom Allah hath given thee as spoils of war, and the daughters of thine uncle on the father's side and the daughters of thine aunts on the father's side, and the daughters of thine uncle on the mother's side and the daughters of thine aunts on the mother's side who emigrated with thee, and a believing woman if she give herself unto the Prophet and the Prophet desire to ask her in marriage - a privilege for thee only, not for the (rest of) believers - We are Aware of that which We enjoined upon them concerning their wives and those whom their right hands possess - that thou mayst be free from blame, for Allah is ever Forgiving, Merciful.

(50) Thou canst defer whom thou wilt of them and receive unto thee whom thou wilt, and whomsoever thou desirest of those whom thou hast set aside (temporarily), it is no sin for thee (to receive her again); that is better; that they may be comforted and not grieve, and may all be pleased with what thou givest them. Allah knoweth what is in your hearts (O men), and Allah is ever Forgiving, Clement.
