Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: One of the noble wives of the Prophet (peace and blessings be upon him) performed ghusl from a vessel, then the Prophet (peace and blessings be upon him) came and began to perform ghusl or perhaps wudu from that vessel. The woman said: O Messenger of Allah! I was in a state of janabah. The Prophet (peace and blessings be upon him) said: Water does not become impure due to janabah.
