Do not say of any thing: "I will do it 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 (It is said) they stayed in the cave three hundred years and nine. 25 You say: "God only knows how long they stayed. He alone knows the secrets of the heavens and the earth. How distinctly He sees and hears! They have no other guardian but Him, and He does not share His authority with any one." 26 Recite what has been revealed to you of the Book of your Lord. There is no one who can change the word of God; and you will not find refuge except in Him. 27 And withhold yourself with those who call on their Lord morning and evening desiring His goodwill, and let not your eyes pass from them, desiring the beauties of this world's life; and do not follow him whose heart We have made unmindful to Our remembrance, and he follows his low desires and his case is one in which due bounds are exceeded. 28 Say: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill 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 These! For them will be 'Adn (Eden) Paradise (everlasting Gardens); wherein rivers flow underneath them, therein they will be adorned with bracelets of gold, and they will wear green garments of fine and thick silk. They will recline therein on raised thrones. How good is the reward, and what an excellent Murtafaqa (dwelling, resting place, etc.)! 31
