Musannaf Ibn Abi Shaybah 11468 — Those who said the one who washes

Aishah bint Sa'd said: Sayyiduna Sa'd (may Allah be pleased with him) was called to the funeral of Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) while he was at al-Baqi'. He came, washed him, shrouded him and then applied perfume to him. Then he came to his house and offered the funeral prayer over him. After that he called for water and took a bath, and said: "I did not bathe because I washed the deceased; had he been impure, I would not have washed him. Rather, I bathed because of the heat."
