never say of anything, "I shall certainly do this tomorrow," 23 Unless Allah pleases; and remember your Lord when you forget and say: Maybe my Lord will guide me to a nearer course to the right 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!

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 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
