Yunus (Jonah) - Description of Jonah's People
Prophet Jonah (Yunus) also known as Dhan-Nun. About his people Almighty Allah said: Was there any town (community) that believed (after seeing the punishment), and its Faith (at that moment) saved it (from the punishment)? (The answer is none,) - except the people of Jonah; when they believed, We removed from them the torment of disgrace in the life of the (present) world, and permitted them to enjoy for a while. Surah 10: 98
The inhabitants of the town of Nineveh were idolators who lived a shameless life. Prophet Jonah was sent to teach them the worship of Allah. The people disliked his interference in their way of worship, so they argued: "We and our forefathers have worshipped these gods for many years and no harm has come to us."
