never say of anything, "I shall certainly do this tomorrow," 23 but only, 'If God will'; and mention thy Lord, when thou forgettest, and say, 'It may be that my Lord will guide me unto something nearer to rectitude than this.' 24 AND [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 25 Say: 'None but Allah knows how long they stayed. To Him belong the Unseen in the heavens and the earth. How well He sees, and how well He hears! They have no other guardian, other than Him, and He allows no one (to share) His rule' 26 And recite that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him. 27 Restrain thyself along with those who cry unto their Lord at morn and evening, seeking His Countenance; and let not thine eyes overlook them, desiring the pomp of the life of the world; and obey not him whose heart We have made heedless of Our remembrance, who followeth his own lust and whose case hath been abandoned. 28 And say: "The truth [has now come] from your Sustainer: let, then, him who wills, believe in it, and let him who wills, reject it." Verily, for all who sin against themselves [by rejecting Our truth] We have readied a fire whose billowing folds will encompass them from all sides; and if they beg for water, they will be given water [hot] like molten lead, which will scald their faces: how dreadful a drink, and how evil a place to rest! 29 Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds. 30 For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade: They will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on! 31
