The Prophet ﷺ turned his face away from him till the man bore witness against himself four times. The Prophet ﷺ said to him, "Are you mad?" He said "No." He said, "Are you married?" He said, "Yes."

The Prophet ﷺ spoke well of him and offered his funeral prayer. (Using translation from Bukhārī 6820)
