And never say about anything: "I shall certainly do this tomorrow" 23 without adding, "if God wills." Recall your Lord if you forget to do something. Say, "I hope that my Lord will provide me better guidance." 24 And they stayed in their Cave three hundred (solar) years, and add nine (for lunar years). 25 Say: 'God knows very well how long they tarried. To Him belongs the Unseen in the heavens and in the earth. How well He sees! How well He hears! They have no protector, apart from Him, and He associates in His government no one.' 26 Read whatever is revealed to you from the Book of your Lord. No one can change His words and you can never find any refuge other than Him. 27 Keep yourself content with those who call upon their Lord, morning and evening, seeking His pleasure, and do not let your eyes pass beyond them. Do you seek the pomp and glitter of the world? Do not follow him whose heart We have caused to be heedless of Our remembrance, and who follows his desires, and whose attitude is of 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 Surely those who believe, and do deeds of righteousness -- surely We leave not to waste the wage of him who does good works; 30 As for such, theirs will be Gardens of Eden, wherein rivers flow beneath them; therein they will be given armlets of gold and will wear green robes of finest silk and gold embroidery, reclining upon throne therein. Blest the reward, and fair the resting-place! 31
