The word(s) "rest" appears 78 time(s) in 75 verse(s) in Quran in Mohsin Khan translation.

(61) Then He completed and finished from their creation (as) seven heavens in two Days and He made in each heaven its affair. And We adorned the nearest (lowest) heaven with lamps (stars) to be an adornment as well as to guard (from the devils by using them as missiles against the devils). Such is the Decree of Him the All-Mighty, the All-Knower.

(62) So know (O Muhammad صلى الله عليه وسلم) that, La ilaha illallah (none has the right to be worshipped but Allah) , and ask forgiveness for your sin, and also for (the sin of) believing men and believing women. And Allah knows well your moving about, and your place of rest (in your homes).

(63) Allah has promised you abundant spoils that you will capture, and He has hastened for you this, 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 the Straight Path.

(64) Wherein both will be Qasirat-ut-Tarf [chaste females (wives) restraining their glances, desiring none except their husbands], with whom no man or jinni has had tamth before them.

(65) These will be the nearest (to Allah).

(66) (There is for him) rest and provision, and a Garden of Delights (Paradise).

(67) Let the rich man spend according to his means; and the man whose resources are restricted, let him spend according to what Allah has given him. Allah puts no burden on any person beyond what He has given him. Allah will grant after hardship, ease.

(68) And indeed We have adorned the nearest heaven with lamps , and We have made such lamps (as) missiles to drive away the Shayatin (devils), and have prepared for them the torment of the blazing Fire.

(69) Unto your Lord (Alone) will be the place of rest that Day.

(70) And We have made your sleep as a thing for rest.
