And those who disbelieved say, "Why has a sign not been sent down to him from his Lord?" Say, [O Muhammad], "Indeed, Allah leaves astray whom He wills and guides to Himself whoever turns back [to Him] - 27 those who believe, and whose hearts find their rest in the remembrance of God - for, verily, in the remembrance of God [men's] hearts do find their rest: 28 The righteously striving believers will receive abundant blessings and the best eternal dwelling. 29 Thus We have sent thee unto a community before whom other communities have passed away, in order that thou mayest recite unto them that which We have revealed unto thee; yet they disbelieve in the Compassionate. Say thou: He is my Lord, there is no god but he; on Him I rely, and unto Him is my return in penitence. 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
