The Unbelievers say: "Why is not a sign sent down to him from his Lord?" Say: "Truly Allah leaveth, to stray, whom He will; But He guideth to Himself those who turn to Him in penitence,- 27 Those who believe and whose hearts are set at rest by the remembrance of Allah; now surely by Allah's remembrance are the hearts set at rest. 28 "As for those who believe and do righteous deeds -- blissful is their end." 29 And thus We have sent you among a nation before which other nations have passed away, that you might recite to them what We have revealed to you and (still) they deny the Beneficent Allah. Say: He is my Lord, there is no god but He; on Him do I rely and to Him is my return. 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
