And never say thou of a thing: verily I am going to do that on the morrow. 23 Without (adding), "if God may please;" and think of your Lord in ease you forget, and say: "Perhaps my Lord will show me a nearer way to rectitude." 24 (It is said) they stayed in the cave three hundred years and nine. 25 Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever. 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 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 Say," Truth comes from your Lord. Let people have faith or disbelieve as they chose." For the unjust We have prepared a fire which will engulf them with its (flames). Whenever they cry for help they will be answered with water as hot as molted brass which will scald their faces. How terrible is such a drink and such a resting place! 29 But surely We do not let the reward of those who believe and do the right to go waste. 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
