Mistakes and sins have come from man and the door of God`s mercy has never been closed for those who repent. But those who think that sin is a pleasure and worship it by considering it as the truth of misguidance and perform such deeds by which they are ashamed, hide their face, their morals will be ruined and misguidance will be considered as truth. The extinction of the nation is not a big deal. But a painful torment like hailstones was never seen or heard. Why would it not be so humiliating and such a great torment, even their sin was so great. A beautiful story, for advice.
