narrated 'abdullah bin 'umar (radi-allahu 'anhu):
the prophet (sallallahu 'alaihi wa sallam) said, "everyone of you is a guardian and everyone of you is responsible (for his wards). a ruler is a
guardian and is responsible (for his subjects); a man is a guardian of his family and responsible (for them); a wife is a guardian of her husband's
house and she is responsible (for it), a slave is a guardian of his master's property and is responsible (for that). beware! all of you are
guardians and are responsible (for your wards)."
