The unbelievers say, 'Why has a sign not been sent down upon him from his Lord?' Say: 'God leads astray whomsoever He will, and He guides to Him all who are penitent.' 27 those who believe, and whose hearts find comfort in the remembrance of Allah. Is it not with the remembrance of Allah that hearts are satisfied. 28 Those who believe and do right: Joy is for them, and bliss (their) journey's end. 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 If only a Koran whereby the mountains were set in motion, or the earth cleaved asunder, or the dead spoken to. No, but to Allah is the affair altogether. Do those who believe know that had Allah willed He could have guided all people? As for those who disbelieve, because of what they do, disaster will not cease to afflict them, or it alights near their home until the promise of Allah comes. Allah will not break His promise. 31
