And those who disbelieved say, "Why has a sign not been sent down to him from his Lord?" Say, [O Muhammad], "Indeed, Allah leaves astray whom He wills and guides to Himself whoever turns back [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 "For those who believe and work righteousness, is (every) blessedness, and a beautiful place of (final) return." 29 That is how We have sent you to a people before whom many a people have come and gone, so that you may announce to them whatever We have revealed to you. But they do not believe in Ar-Rahman. Tell them: "He is my Lord. There is no other god but He. In Him have I placed my trust, and to Him is my reversion." 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
