Those who have rejected (the message of Muhammad) say: "Why has no sign been sent down upon him from his Lord?" Tell them: "Allah lets go astray those whom He wills, and guides to Himself those who turn to Him." 27 Who have believed and whose hearts have rest in the remembrance of Allah. Verily in the remembrance of Allah do hearts find rest! 28 of those who believe and do righteous deeds; theirs is blessedness and a fair resort. 29 Similarly We sent you (O dear Prophet Mohammed – peace and blessings be upon him) towards the nation, before whom other nations have passed away, for you to recite to them the divine revelations We sent down to you, whereas they are denying the Most Gracious; proclaim, “He is my Lord – there is no worship except for Him; I rely only upon Him and only towards 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
