And never say about anything: "I shall certainly do this 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 they stayed in their Cave three hundred (solar) years, and add nine (for lunar years). 25 Say: "God knows best how long they remained [there]. His [alone] is the knowledge of the hidden reality of the heavens and the earth: how well does He see and hear! No guardian have they apart from Him, since He allots to no one a share in His rule!" 26 Recite what has been revealed to thee of the Book of thy Lord; no man can change His words. Apart from Him, thou wilt find no refuge. 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 And proclaim, “The Truth is from your Lord”; so whoever wills may accept faith, and whoever wills may disbelieve – We have indeed prepared for the disbelievers a fire the walls of which will surround them; if they plead for water, their plea will be answered with water like molten metal which shall scald their faces; what an evil drink it is; and what an evil destination is hell! 29 As for those who believe and do good deeds, We do not let the reward of anyone who does a good deed go to 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
