And do not say, regarding anything, 'I am going to do that 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 three hundred (solar) years, and add nine (for lunar years). 25 Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector, etc.) other than Him, and He makes none to share in His Decision and His Rule." 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 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 And say: "The truth [has now come] from your Sustainer: let, then, him who wills, believe in it, and let him who wills, reject it." Verily, for all who sin against themselves [by rejecting Our truth] We have readied a fire whose billowing folds will encompass them from all sides; and if they beg for water, they will be given water [hot] like molten lead, which will scald their faces: how dreadful a drink, and how evil a place to rest! 29 As for those who believe and do good deeds, We do not let the reward of anyone who does a good deed go to waste, 30 These! for them are Gardens Everlasting whereunder rivers flow; bedecked they shall be therein with bracelets of gold, and wear they shall green robes of satin and brocade, reclining therein on the couches; excellent the reward, and goodly the resting-place! 31
