Musannaf Ibn Abi Shayba 1:1512

Ibn ‘Ulayyah narrated to us, from Isra’il, from al-Zibriqan, who said: Ka’b ibn ‘Abd Allah narrated to us. He said: We were with Hudhayfah, and we arrived at a pool of water in which there was carrion and in which a menstruating woman would bathe. He said: Water does not become impure.
