never say of anything, "I shall certainly do this tomorrow," 23 Except if Allah will. And remember thy Lord when thou forgettest, and say: It may be that my Lord guideth me unto a nearer way of truth 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 And recite the Book of your Lord which has been divinely revealed to you; there is none who can change His Words; and you will never find a 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, "This is the truth from your Lord. Let him who will, believe in it, and him who will, deny it." For the wrongdoers We have prepared a Fire which will cover them like a canopy, and if they beg for water, they will be given water as hot as molten lead, which will scald their faces: how dreadful a drink, and how evil a resting place! 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 they shall dwell in the Gardens of eternity where rivers flow at their feet. Reclining upon raised couches, they will be adorned with bracelets of gold, and will wear green robes of fine silk and heavy brocade. An excellent reward and an excellent resting place! 31
