Do not say of any thing: "I will 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 they tarried in their cave three hundred years and added nine. 25 Say, "God knows best how long they stayed in it." Only God has knowledge of the unseen in the heavens and on the earth. How well He sees and how well He hears! Man has no other guardian besides Him. He allows none to share His sovereignty. 26 And recite, [O Muhammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge. 27 And restrain thyself with those who call upon their Lord at morning and evening, desiring His countenance, and let not thine eyes turn away from them, desiring the adornment of the present life; and obey not him whose heart We have made neglectful of Our remembrance so that he follows his own lust, and his affair has become all excess. 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
