The unbelievers say: "How is it that no miracle was sent down to him by his Lord?" Say: "God leads whosoever He wills astray, and guides whoever turns to Him in repentance. 27 “Those who accepted faith and whose hearts gain solace from the remembrance of Allah; pay heed! Only in the remembrance of Allah is the solace of hearts!” 28 "For those who believe and work righteousness, is (every) blessedness, and a beautiful place of (final) return." 29 We have sent you to a nation before whom there lived many nations so that you would read to them what We have revealed to you. They still deny the existence of the Beneficent God. Say, "He is my Lord besides whom there is no other God. I trust Him and turn to Him in repentance." 30 And if there was any qur'an by which the mountains would be removed or the earth would be broken apart or the dead would be made to speak, [it would be this Qur'an], but to Allah belongs the affair entirely. Then have those who believed not accepted that had Allah willed, He would have guided the people, all of them? And those who disbelieve do not cease to be struck, for what they have done, by calamity - or it will descend near their home - until there comes the promise of Allah. Indeed, Allah does not fail in [His] promise. 31
