Sayyida Umm Salama (may Allah be pleased with her) narrates that she asked: O Messenger of Allah! I tightly braid my hair on my head, so should I undo it at the time of ghusl after sexual impurity? He replied: It is sufficient that you pour water over your head three times, then pour water over your entire body, you will become pure. Or he said: If you do so, you will become pure.
