Those who deny the truth ask, "Why has no Sign been sent down to him by his Lord?" Say, "God lets go astray those whom He wills and guides to Himself those who turn to Him, 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 Those who believe (in the Oneness of Allah - Islamic Monotheism), and work righteousness, Tuba (it means all kinds of happiness or name of a tree in Paradise) is for them and a beautiful place of (final) return. 29 We have sent you to a nation before whom there lived many nations so that you would read to them what We have revealed to you. They still deny the existence of the Beneficent God. Say, "He is my Lord besides whom there is no other God. I trust Him and turn to Him in repentance." 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
