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

(51) And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise.

(52) Hell, where they will burn, an evil resting-place.

(53) Allah hath (now) revealed the fairest of statements, a Scripture consistent, (wherein promises of reward are) paired (with threats of punishment), whereat doth creep the flesh of those who fear their Lord, so that their flesh and their hearts soften to Allah's reminder. Such is Allah's guidance, wherewith He guideth whom He will. And him whom Allah sendeth astray, for him there is no guide.

(54) And verily, if thou shouldst ask them: Who created the heavens and the earth? they will say: Allah. Say: Bethink you then of those ye worship beside Allah, if Allah willed some hurt for me, could they remove from me His hurt; or if He willed some mercy for me, could they restrain His mercy? Say: Allah is my all. In Him do (all) the trusting put their trust.

(55) 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.

(56) Allah it is Who hath appointed for you night that ye may rest therein, and day for seeing. Lo! Allah is a Lord of bounty for mankind, yet most of mankind give not thanks.

(57) Who made the earth a resting-place for you, and placed roads for you therein, that haply ye may find your way;

(58) And leave the sea behind at rest, for lo! they are a drowned host.

(59) So know (O Muhammad) that there is no Allah save Allah, and ask forgiveness for thy sin and for believing men and believing women. Allah knoweth (both) your place of turmoil and your place of rest.

(60) When those who disbelieve had set up in their hearts zealotry, the zealotry of the Age of Ignorance, then Allah sent down His peace of reassurance upon His messenger and upon the believers and imposed on them the word of self-restraint, for they were worthy of it and meet for it. And Allah is Aware of all things.
