Nor say of anything, "I shall be sure to do so and so tomorrow"- 23 Unless Allah pleases; and remember your Lord when you forget and say: Maybe my Lord will guide me to a nearer course to the right than this. 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 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 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 Say: 'The truth is from your Lord; so let whosoever will believe, and let whosoever will disbelieve.' Surely We have prepared for the evildoers a fire, whose pavilion encompasses them; if they call for succour, they will be succoured with water like molten copper, that shall scald their faces -- how evil a potion, and how evil a resting-place! 29 As for those who believe and do good We shall not cause their reward to be lost. 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
