It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that one of the noble wives of the Prophet (peace and blessings be upon him) performed ghusl (ritual bath) for janabah, and the Prophet (peace and blessings be upon him) performed ghusl or wudu with the leftover water from her. That wife asked the Prophet (peace and blessings be upon him) about this, so the Prophet (peace and blessings be upon him) said, "Nothing makes water impure."
