And never say about anything: "I shall certainly do this 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 They remained in the Cave for three hundred years; and others added nine more years. 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 And recite, [O Muhammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge. 27 And be patient with those who call to their Lord in the morning and evening, desiring His Face. And do not turn your eyes away from them desiring the good things of this life, nor obey he whose heart We have made neglectful of Our remembrance; so that he follows his own lust, and his affair has become excessive. 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 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 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
