Chapter: Tying the person liable to do mischievous things
Narrated Abu Huraira:
Allah's Messenger (ﷺ) sent horsemen to Najd and they arrested and brought a man called Thumama bin Uthal, the chief of Yamama, and they fastened him to one of the pillars of the Mosque. When Allah's Apostle came up to him; he asked, "What have you to say, O Thumama?" He replied, "I have good news, O Muhammad!" Abu Huraira narrated the whole narration which ended with the order of the Prophet "Release him!"
