And never say of anything, "I shall do such and such thing 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 [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 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 Recite what has been revealed to thee of the Book of thy Lord; no man can change His words. Apart from Him, thou wilt find no refuge. 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 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 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 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
