The unbelievers say, 'Why has a sign not been sent down upon him from his Lord?' Say: 'God leads astray whomsoever He will, and He guides to Him all who are penitent.' 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 So those who believe (in the message of the Truth) and do good are destined for happiness and a blissful end. 29 Thus have we sent thee amongst a People before whom (long since) have (other) Peoples (gone and) passed away; in order that thou mightest rehearse unto them what We send down unto thee by inspiration; yet do they reject (Him), the Most Gracious! Say: "He is my Lord! There is no god but He! On Him is my trust, and to Him do I turn!" 30 Even if the Quran would make mountains move, cut the earth into pieces and make the dead able to speak, (the unbelievers still would not believe). All affairs are in the hands of God. Do the believers still hope that they will believe? Had God wanted he could have guided the whole of mankind to the right path. The unbelievers will always suffer afflictions that result from their deeds or the affliction which occur near their homes, until God's promise of punishing them will be fulfilled. God does not disregard His promise. 31
