(13:26) Allah extends provision for whom He wills and restricts [it]. And they rejoice in the worldly life, while the worldly life is not, compared to the Hereafter, except [brief] enjoyment. (13:27) 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] - (13:28) Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured." (13:29) Those who have believed and done righteous deeds - a good state is theirs and a good return. (13:30) Thus have We sent you to a community before which [other] communities have passed on so you might recite to them that which We revealed to you, while they disbelieve in the Most Merciful. Say, "He is my Lord; there is no deity except Him. Upon Him I rely, and to Him is my return." (13:31) And if there was any qur`an by which the mountains would be removed or the earth would be broken apart or the dead would be made to speak, [it would be this Qur`an], but to Allah belongs the affair entirely. Then have those who believed not accepted that had Allah willed, He would have guided the people, all of them? And those who disbelieve do not cease to be struck, for what they have done, by calamity - or it will descend near their home - until there comes the promise of Allah. Indeed, Allah does not fail in [His] promise. (13:32) And already were [other] messengers ridiculed before you, and I extended the time of those who disbelieved; then I seized them, and how [terrible] was My penalty.
