Do not say of anything: 'I will do it 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 So they stayed in their Cave three hundred years, and (some) add nine (more) 25 You say: "God only knows how long they stayed. He alone knows the secrets of the heavens and the earth. How distinctly He sees and hears! They have no other guardian but Him, and He does not share His authority with any one." 26 (O Prophet), recite to them from the Book of your Lord what has been revealed to you for none may change His words; (and were you to make any change in His words) you will find no refuge from 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 As for those who believe and do good We shall not cause their reward to be lost. 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
