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 (in the Oneness of Allah - Islamic Monotheism), and whose hearts find rest in the remembrance of Allah, Verily, in the remembrance of Allah do hearts find rest. 28 The righteously striving believers will receive abundant blessings and the best eternal dwelling. 29 Thus We send thee (O Muhammad) unto a nation, before whom other nations have passed away, that thou mayst recite unto them that which We have inspired in thee, while they are disbelievers in the Beneficent. Say: He is my Lord; there is no Allah save Him. In Him do I put my trust and unto Him is my recourse. 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
