Nor say of anything, "I shall be sure to do so and so 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 tarried in their cave three hundred years and added nine. 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 And recite that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him. 27 And contain thyself in patience by the side of all who at morn and at evening invoke their Sustainer, seeking His countenance, and let not thine eyes pass beyond them in quest of the beauties of this world's life; and pay no heed to any whose heart We have rendered heedless of all remembrance of Us because he had always followed [only] his own desires, abandoning all that is good and true. 28 Say: 'The truth is from your Lord; so let whosoever will believe, and let whosoever will disbelieve.' Surely We have prepared for the evildoers a fire, whose pavilion encompasses them; if they call for succour, they will be succoured with water like molten copper, that shall scald their faces -- how evil a potion, and how evil a resting-place! 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 For them are everlasting Gardens of Eden, beneath which rivers flow – in it they will be given bracelets of gold to adorn, and shall wear green clothes made of fine silk and gold embroidery, reclining upon thrones in it; what an excellent reward; and what an excellent abode is Paradise! 31
