NOW THOSE who are bent on denying the truth [of the Prophet's message] say: "Why has no miraculous sign ever been bestowed upon him from on high by his Sustainer?" Say: "Behold, God lets go astray him who wills [to go astray,] just as He guides unto Himself all who turn unto Him 27 They are those who believe and whose hearts find rest in the remembrance of Allah. Lo! in the remembrance of Allah hearts do find rest. 28 “Those who accepted faith and did good deeds – for them is joy and an excellent outcome.” 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 if there were a Qur'an whereby the mountains could be moved or whereby the earth could be traversed or whereby the dead could be spoken to, it would be in vain. Aye! the affair belongeth to Allah entirely. Have not then those who believe yet known? that had Allah willed, He would have guided all mankind! And a rattling adversity ceaseth not to befall those who disbelieve for that which they have wrought or to alight nigh unto their habitation until Allah's promise cometh; verily Allah faileth not the tryst. 31
