And never say thou of a thing: verily I am going to do that on the morrow. 23 without [adding,] "if God so wills." And if thou shouldst forget [thyself at the time, and become aware of it later,] call thy Sustainer to mind and say: "I pray that my Sustainer guide me, even closer than this, to a consciousness of what is right!" 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 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 Proclaim what has been revealed to you from your Lord's Book. None can change His words. You shall find no refuge besides 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 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 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 Those, they shall live in the Gardens of Eden, underneath which rivers flow. They shall be adorned with bracelets of gold and arrayed in green garments of silk, and brocade, reclining therein on couches; how excellent is their reward and how fine is their resting place! 31
