Sahih Bukhari Volume 7, Book 62, Hadith Number 128.

Narrated By Ibn ‘Umar : The Prophet said, “All of you are guardians and are responsible for your wards. The ruler is a guardian and the man is a guardian of his family; the lady is a guardian and is responsible for her husband’s house and his offspring; and so all of you are guardians and are responsible for your wards.”
