And never say of anything, "I shall do such and such thing tomorrow." 23 unless Allah should will it. And should you forget (and make such a statement), remember your Lord and say: "I expect my Lord to guide me to what is nearer to rectitude than this." 24 And they stayed in their Cave for three hundred years* and nine more*. (* 300 according to the Solar calendar and 309 according to the Lunar calendar.) 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 Proclaim what has been revealed to you from your Lord's Book. None can change His words. You shall find no refuge besides Him. 27 And restrain thyself with those who call upon their Lord at morning and evening, desiring His countenance, and let not thine eyes turn away from them, desiring the adornment of the present life; and obey not him whose heart We have made neglectful of Our remembrance so that he follows his own lust, and his affair has become all excess. 28 Say, "The truth is from your Lord": Let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on! 29 As for those who believe and do good works We do not waste the wage of whosoever does good works. 30 those -- theirs shall be Gardens of Eden, underneath which rivers flow; therein they shall be adorned with bracelets of gold, and they shall be robed in green garments of silk and brocade, therein reclining upon couches -- O, how excellent a reward! And O, how fair a resting-place! 31
