And never say of anything, "I shall do such and such thing tomorrow." 23 Except [when adding], "If Allah wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct." 24 So they stayed in their Cave three hundred years, and (some) add nine (more) 25 Say: Allah knows best how long they remained; to Him are (known) the unseen things of the heavens and the earth; how clear His sight and how clear His hearing! There is none to be a guardian for them besides Him, and He does not make any one His associate in His Judgment. 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 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 [But,] behold, as for those who attain to faith and do righteous deeds - verily, We do not fail to requite any who persevere in doing good: 30 They shall dwell in the Gardens of Eternity, beneath which streams flow. There they will be adorned with bracelets of gold, will be arrayed in green garments of silk and rich brocade, and will recline on raised couches. How excellent is their reward, and how nice their resting-place!" 31
