The unbelievers say, "Why have not some miracles been sent to him, (Muhammad), from his Lord." Say, "God causes whomever He wants to go astray and He guides those who turn to Him in repentance 27 Those who believe and find peace in their hearts from the contemplation of God: Surely there is peace of heart in the contemplation of God!" 28 [and so it is that] they who attain to faith and do righteous deeds are destined for happiness [in this world] and the most beauteous of all goals [in the life to come]!" 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
