Do not say of any thing: "I will do it tomorrow," 23 without adding, "if God wills." Recall your Lord if you forget to do something. Say, "I hope that my Lord will provide me better guidance." 24 And they remained in their cave three hundred years and (some) add (another) nine. 25 Say: 'God knows very well how long they tarried. To Him belongs the Unseen in the heavens and in the earth. How well He sees! How well He hears! They have no protector, apart from Him, and He associates in His government no one.' 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 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 thou: the truth is from your Lord; let him therefore who will, believe, and let him who will, disbelieve. Verily We have gotten ready for the wrong-doers a Fire the awnings whereof shall encompass them; and if they cry for relief they shall be relieved with water like the dregs of oil scalding their faces. Ill the drink, and vile the resting-place! 29 Surely those who believe, and do deeds of righteousness -- surely We leave not to waste the wage of him who does good works; 30 theirs shall be gardens of perpetual bliss - [gardens] through which running waters flow - wherein they will be adorned with bracelets of gold and will wear green garments of silk and brocade, [and] wherein upon couches they will recline:" how excellent a recompense, and how goodly a place to rest! 31
