And do not say, regarding anything, 'I am going to do that tomorrow,' 23 Except if Allah will. And remember thy Lord when thou forgettest, and say: It may be that my Lord guideth me unto a nearer way of truth than this. 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 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 And recite what has been revealed to you of the Book of your Lord, there is none who can alter His words; and you shall not find any refuge besides Him. 27 And withhold yourself with those who call on their Lord morning and evening desiring His goodwill, and let not your eyes pass from them, desiring the beauties of this world's life; and do not follow him whose heart We have made unmindful to Our remembrance, and he follows his low desires and his case is one in which due bounds are exceeded. 28 Say: "The truth is from your Lord: So believe if you like, or do not believe if you will." We have prepared for the sinners a fire which will envelope them in its tent. If they ask for water they will be helped to liquid like molten brass that would scald their mouths. How evil the drink, and evil the resting-place! 29 Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds. 30 Those will have gardens of perpetual residence; beneath them rivers will flow. They will be adorned therein with bracelets of gold and will wear green garments of fine silk and brocade, reclining therein on adorned couches. Excellent is the reward, and good is the resting place. 31
