It is narrated from Sayyidah Umm Hani (may Allah be pleased with her) that: "When the Messenger of Allah (peace and blessings be upon him) conquered Makkah, water was brought to him, and the people screened him; he (peace and blessings be upon him) took a bath, then prayed eight rak'ahs, which no one ever saw him pray afterwards."
