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 (As for) those who believe and do good, a good final state shall be theirs and a goodly return. 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 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
