And never say about anything: "I shall certainly 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 knows best how long they remained in it, for only He knows all that is hidden in the heavens and the earth. How well He sees; how well He hears! The creatures have no other guardian than Him; He allows none to share His authority." 26 Read whatever is revealed to you from the Book of your Lord. No one can change His words and you can never find any refuge other than Him. 27 And keep thy soul content with those who call on their Lord morning and evening, seeking His Face; and let not thine eyes pass beyond them, seeking the pomp and glitter of this Life; nor obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds. 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 As to those who believe and work righteousness, verily We shall not suffer to perish the reward of any who do a (single) righteous deed. 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
