The unbelievers say: "How is it that no miracle was sent down to him by his Lord?" Say: "God leads whosoever He wills astray, and guides whoever turns to Him in repentance. 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 "For those who believe and work righteousness, is (every) blessedness, and a beautiful place of (final) return." 29 Thus have We sent you (O Muhammad SAW) to a community before whom other communities have passed away, in order that you might recite unto them what We have inspired to you, while they disbelieve in the Most Beneficient (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance." 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
