From Sahih Bukhari (Hadith 6097):
Narrated Hudhaifa:From among the people, Ibn Um `Abd greatly resembled Allah's Messenger (ﷺ) in solemn gate and good appearance of piety and in calmness and sobriety from the time he goes out of his house till he returns to it. But we do not know how he behaves with his family when he is alone with them
