A man came to the Prophet and said, ‘O Messenger of God! Who among the people is the most worthy of my good companionship? The Prophet said: Your mother. The man said, ‘Then who?' The Prophet said: Then your mother. The man further asked, ‘Then who?' The Prophet said: Then your mother. The man asked again, ‘Then who?' The Prophet said: Then your father. (Bukhari, Muslim).
