From ‘Umar (radiyAllâhu ‘anhu) who said that Allâh’s Messenger (salAllâhu ‘alaihi wa’sallam) said:

Each of you is a guardian and is responsible for those whom he is in charge of. So the ruler is a guardian and is responsible for his subjects; a man is the guardian of his family and is responsible for those under his care; a woman is a guardian of her husband’s home and is responsible for those under her care; a servant is the guardian of his master’s wealth and is responsible for that which he is entrusted with; and a man is the guardian of his father’s wealth and is responsible fore what is under his care. So each one of you is a guardian and is responsible for what he is entrusted with.”
