Nor say of anything, "I shall be sure to do so and so tomorrow"- 23 Except (with the saying), "If Allah will!" And remember your Lord when you forget and say: "It may be that my Lord guides me unto a nearer way of truth than this." 24 They, in fact, stayed in the cave for three hundred plus nine further years. 25 Say, "Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone." 26 Recite what has been revealed to you of the Book of your Lord. There is no one who can change the word of God; and you will not find refuge except in 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 The righteously striving believers should know that We do not neglect the reward of those who do good deeds. 30 There will be gardens of Eden for them, with rivers flowing by, where they will be decked in bracelets of gold, with silken robes of green and of brocades to wear, reclining on couches. How excellent the guerdon, and excellent the resting-place! 31
