never say of anything, "I shall certainly do this tomorrow," 23 Without adding, "So please Allah!" and call thy Lord to mind when thou forgettest, and say, "I hope that my Lord will guide me ever closer (even) than this to the right road." 24 And they remained in their cave for three hundred years and exceeded by nine. 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 (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 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 28 And say: The truth is from your Lord, so let him who please believe, and let him who please disbelieve; surely We have prepared for the iniquitous a fire, the curtains of which shall encompass them about; and if they cry for water, they shall be given water like molten brass which will scald their faces; evil the drink and ill the resting-place. 29 The righteously striving believers should know that We do not neglect the reward of those who do good deeds. 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
