And those who disbelieve say: 'Why has no sign been sent down to him by his Lord' Say: 'Allah leads astray whom He will, and guides those who repent, 27 Those who believe and whose hearts are set at rest by the remembrance of Allah; now surely by Allah's remembrance are the hearts set at rest. 28 “Those who accepted faith and did good deeds – for them is joy and an excellent outcome.” 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 Yet even if [they should listen to] a [divine] discourse by which mountains could be moved, or the earth cleft asunder, or the dead made to speak - [they who are bent on denying the truth would still refuse to believe in it]! Nay, but God alone has the power to decide what shall be. Have, then, they who have attained to faith not yet come to know that, had God so willed; He would indeed have guided all mankind aright? But as for those who are bent on denying the truth - in result of their [evil] deeds, sudden calamities will always befall them or will alight close to their homes; [and this will continue] until God's promise [of resurrection] is fulfilled: verily, God never fails to fulfil His promise! 31
