Never say of something, "I shall do it tomorrow," 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 AND [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 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 recite (and teach) what has been revealed to thee of the Book of thy Lord: none can change His Words, and none wilt thou find as a refuge other than Him. 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: "The truth is from your Lord: So believe if you like, or do not believe if you will." We have prepared for the sinners a fire which will envelope them in its tent. If they ask for water they will be helped to liquid like molten brass that would scald their mouths. How evil the drink, and evil the resting-place! 29 Verily those who believe and work the righteous works - verily We waste not the hire of one who doth well in regard to his work. 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
