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 stayed in their Cave three hundred (solar) years, and add nine (for lunar years). 25 (Muhammad), say, "God knows best how long they stayed there; to Him belongs the unseen of both the heavens and the earth. How clear is His sight and how keen His hearing! No one other than Him is their guardian and no one shares His Judgment. 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 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 And say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place. 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 As for such, theirs will be Gardens of Eden, wherein rivers flow beneath them; therein they will be given armlets of gold and will wear green robes of finest silk and gold embroidery, reclining upon throne therein. Blest the reward, and fair the resting-place! 31
