Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says that the Messenger of Allah (peace and blessings be upon him) said: "Each of you is a guardian, and each of you will be questioned. The ruler is a guardian over the people and will be questioned about the public. The head of the household is answerable for his family and will be questioned about his family; the woman is the guardian of her husband's house and will be questioned about it; and a man's slave is the keeper of his master's wealth and will be questioned about it. Each one of you is a guardian, and each one of you will be questioned."
