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 Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured." 28 Those who believe and work righteous works, for them is bliss and a happy resort. 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 Even if there were a Quran by which mountains could be set in motion, by which the earth could be rent asunder, or by which the dead could be made to speak [they would not believe in it]. Surely all things are subject to God's will. Are the faithful unaware that, had He pleased, God could have guided all mankind? Calamity shall not cease to strike those who deny the truth because of their misdeeds or to strike near their homes, until God's promise be fulfilled. God will not fail to keep His promise. 31
