The Prophet Muhammad (may peace be upon him) said: "Every one of you is a caretaker, and is responsible for his consignment. The ruler is ...

... a caretaker of people, and is responsible for his subjects. A man is a caretaker of his family, and is responsible for them. A woman is a caretaker of her husband's house and children, and is responsible for them. A slave is a caretaker of his master's property, and is responsible for it. All of you are caretakers, and all of you are responsible for their consignment."
