Those who disbelieve say: If only a portent were sent down upon him from his Lord! Say: Lo! Allah sendeth whom He will astray, and guideth unto Himself all who turn (unto Him), 27 those who believe, and whose hearts find comfort in the remembrance of Allah. Is it not with the remembrance of Allah that hearts are satisfied. 28 Those who have believed and done righteous deeds - a good state is theirs and a good 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 Had there been a Qur'an which could have made the mountains move, or the earth to cleave asunder, or the dead to speak, yet all authority belongs to God. Have the believers not learnt that if God had so willed He could have guided all mankind? As for unbelievers, they will be visited by misfortune endlessly for what they have done; or it would sit in their homes till the promised threat of God comes to pass. Surely God does not go back on His promise. 31
