Yahya bin Sa'id said: I asked Amrah about the ritual bath on Friday, and she said: I asked Sayyidah Aishah (may Allah be pleased with her) about the ritual bath on Friday, and she said: "The people used to do their own work, and they would go (to the Friday prayer) in that same state, so it was said to them: 'If only you would take a ritual bath (it would be much better).'"
