And never say about anything: "I shall certainly do this tomorrow" 23 without adding, "if God wills." Recall your Lord if you forget to do something. Say, "I hope that my Lord will provide me better guidance." 24 They, in fact, stayed in the cave for three hundred plus nine further years. 25 Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector, etc.) other than Him, and He makes none to share in His Decision and His Rule." 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 Be patient with those who worship their Lord in the mornings and evenings to seek His pleasure. Do not overlook them to seek the worldly pleasures. Do not obey those whom We have caused to neglect Us and instead follow their own desires beyond all limits. 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 But surely We do not let the reward of those who believe and do the right to go waste. 30 For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade: They will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on! 31
