39:23 Allah has revealed (the) best (of) [the] statement - a Book (its parts) resembling each ot oft-repeated. Shiver from it (the) skins (of) those who fear their Lord, then relax their skins and their hearts at (the) remembrance (of) Allah. That (is the) guidance (of) Allah, He guides with it whom He wills. And whoever lets go astray Allah then not for him any guide.
