Al-Adab al-Mufrad 3

Bahz ibn Hakim's grandfather said, "I asked, 'Messenger of Allah, to whom should I be dutiful?' 'Your mother,' he replied. I asked, 'Then whom?' 'Your mother,' he replied. I asked, 'Then whom?' 'Your mother,' he replied. I asked, 'Then to whom should I be dutiful?' 'Your father,' he replied, 'and then the next closest relative and then the next.'"
