And say not of anything: Lo! I shall do that tomorrow, 23 Except [when adding], "If Allah wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct." 24 So they stayed in their Cave three hundred years, and (some) add nine (more) 25 Say: "Allah knows best how long they remained in it, for only He knows all that is hidden in the heavens and the earth. How well He sees; how well He hears! The creatures have no other guardian than Him; He allows none to share His authority." 26 AND CONVEY [to the world] whatever has been revealed to thee of thy Sustainer's writ. There is nothing that could alter His words; and thou canst find no refuge other than with Him. 27 And keep thy soul content with those who call on their Lord morning and evening, seeking His Face; and let not thine eyes pass beyond them, seeking the pomp and glitter of this Life; nor obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds. 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 Verily! As for those who believe and do righteous deeds, certainly! We shall not suffer to be lost the reward of anyone who does his (righteous) deeds in the most perfect manner. 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
