AND NEVER say about anything, "Behold, I shall 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 (It is said) they stayed in the cave three hundred years and nine. 25 Say, "Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone." 26 Recite what has been revealed to thee of the Book of thy Lord; no man can change His words. Apart from Him, thou wilt find no refuge. 27 And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His countenance. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect. 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 The righteously striving believers should know that We do not neglect the reward of those who do good deeds. 30 These! for them are Gardens Everlasting whereunder rivers flow; bedecked they shall be therein with bracelets of gold, and wear they shall green robes of satin and brocade, reclining therein on the couches; excellent the reward, and goodly the resting-place! 31
