A man from among the companions of the Prophet ﷺ entered the mosque and found Kaab telling stories to the people. He asked, "Who is this?"They replied, "It is Kaab, telling stories."He said, "I heard the Messenger of Allah ﷺ say, 'No one should tell stories publicly except a ruler, one appointed by a ruler, or someone showing off.'"Word of this reached Kaab, and he was never seen telling stories again.
