Narrated Abdullah bin 'Umar (Radi-Allahu 'anhu):

I heard Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) saying, "Everyone of
you is a guardian, and responsible for what is in his custody. The ruler is
a guardian of his subjects and responsible for them; a husband is a
guardian of his family and is responsible for it; a lady is a guardian of
her husband's house and is responsible for it, and a servant is a guardian
of his master's property and is responsible for it." I heard that from
Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) and I think that the Prophet
also said, "A man is a guardian of his father's property and is responsible
for it, so all of you are guardians and responsible for your wards and
things under your care."
