Why do torments come?

Did the people of the towns then feel secure against the coming of Our Punishment by night while they are asleep?

Or, did the people of the towns then feel secure against the coming of Our Punishment in the forenoon while they were playing?

Did they then feel secure against the Plan of Allâh? None feels secure from the Plan of Allâh except the people who are the losers.

Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not?

Those are the towns We narrate to you their important events. Surely their messengers came to them with clear signs, but they were not able to believe in what they had rejected earlier. This is how Allah seals the hearts of the disbelievers.
