Do not say of any thing: "I will do it tomorrow," 23 Without (adding), "if God may please;" and think of your Lord in ease you forget, and say: "Perhaps my Lord will show me a nearer way to rectitude." 24 And they remained in their cave three hundred years and (some) add (another) 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 And recite the Book of your Lord which has been divinely revealed to you; there is none who can change His Words; and you will never find a refuge besides 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 Lo! as for those who believe and do good works - Lo! We suffer not the reward of one whose work is goodly to be lost. 30 For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade: They will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on! 31
