Asim bin Amr Bajali narrates from the man who was among those who asked Sayyiduna Umar bin Khattab (may Allah be pleased with him): We have come to you to ask about three things: What is the ruling on a servant performing voluntary prayers in his house, what is the method of ghusl (ritual bath) after janabah (major impurity), and what is permissible for a husband regarding his menstruating wife. Sayyiduna Umar (may Allah be pleased with him) said: Are you people magicians? You have asked me such questions that, since I asked the Messenger of Allah (peace and blessings be upon him) about them, no one has asked me these questions. Nevertheless, the Messenger of Allah (peace and blessings be upon him) said: A servant performing voluntary prayers in his house is light; he may illuminate his house as much as he wishes. Regarding ghusl after janabah, he said: The person in a state of janabah should wash his private parts, then perform wudu, and pour water over his head three times. And regarding the menstruating woman, he said: The part above her izar (waist-wrapper) is permissible for the husband.
