Those who deny the truth ask, "Why has no Sign been sent down to him by his Lord?" Say, "God lets go astray those whom He wills and guides to Himself those who turn to Him, 27 those who believe and whose hearts find comfort in the remembrance of God -- surely in the remembrance of God hearts can find comfort. 28 Those who believe and do the right, have happiness, and an excellent resting place. 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 were such a Qur’an to come that would cause the mountains to move, or the earth to split asunder, or the dead to speak, even then these disbelievers would not believe; in fact, all matters are only at Allah’s discretion; so have not the Muslims despaired in that, had Allah willed, He would have guided all mankind? Disasters shall continue to strike the disbelievers on account of their deeds, or descend near their homes until Allah’s promise comes; indeed Allah does not break the promise. 31
