Musannaf Ibn Abi Shaybah 11465 — Those who said the one who washes

Sa'id bin Jubayr said: My honoured mother, after washing a deceased person, said to me: "Ask and tell me: is a ritual bath due on me?" So I came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and asked him. He said: "Was it something impure that your mother washed (that she should now bathe herself)?"
