Ka'b said that when Jeremiah delivered the message of his Lord, and the people heard the threats and warnings in it, they said: "You are lying, if you are saying that Allah shall destroy the land, His temple, His Book, His worship, and monotheism." They captured Jeremiah, tied him up, and imprisoned him. At this, Allah sent Nebuchadnezzar upon them. He entered the country with his troops and surrounded the city. When the siege was prolonged they surrendered to his rule. They opened the gates and Nebuchadnezzar's troops streamed in.
