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, "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 And rehearse thou that which hath been revealed unto thee of the Book of thy Lord; and none may alter His Words, and never wilt thou find beside Him a covert. 27 Persevere with those who call on their Lord morning and evening, seeking His magnificence. Do not turn your eyes away from them, seeking the splendours of this world, and do not follow him whose heart We have made oblivious to Our remembrance, who follows his own lust and exceeds the bound. 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 Verily! As for those who believe and do righteous deeds, certainly! We shall not suffer to be lost the reward of anyone who does his (righteous) deeds in the most perfect manner. 30 They will be admitted to the gardens of Eden wherein streams flow. They will rest on soft couches, decked with bracelets of gold and clothed in green silk garments and shining brocade. How blissful is such a reward and resting place! 31
