And never say about anything that, “I will do this 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 Say: 'God knows very well how long they tarried. To Him belongs the Unseen in the heavens and in the earth. How well He sees! How well He hears! They have no protector, apart from Him, and He associates in His government no one.' 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 contain thyself in patience by the side of all who at morn and at evening invoke their Sustainer, seeking His countenance, and let not thine eyes pass beyond them in quest of the beauties of this world's life; and pay no heed to any whose heart We have rendered heedless of all remembrance of Us because he had always followed [only] his own desires, abandoning all that is good and true. 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 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
