The Unbelievers say: "Why is not a sign sent down to him from his Lord?" Say: "Truly Allah leaveth, to stray, whom He will; But He guideth to Himself those who turn to Him in penitence,- 27 “Those who accepted faith and whose hearts gain solace from the remembrance of Allah; pay heed! Only in the remembrance of Allah is the solace of hearts!” 28 Those who believe and work righteous works, for them is bliss and a happy resort. 29 Thus have We sent you as a Messenger to a community before which many other communities have passed away that you may recite to them whatever We have revealed to you. And yet they deny the Lord of Mercy. Say to them: "He is my Lord, there is no god but Him. In Him I have placed all my trust and to Him I shall return." 30 And if there had been a Quran with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Quran). But the decision of all things is certainly with Allah. Have not then those who believe yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieve because of their (evil) deeds or it (i.e. the disaster) settle close to their homes, until the Promise of Allah comes to pass. Certainly, Allah does not fail in His Promise. 31
