Musa bin Anas (may Allah have mercy on him) says that al-Hajjaj bin Yusuf addressed the people, saying: Wash your faces, your hands and your feet, and wash their outer parts, inner parts and upper parts, for this is closer to your Paradise (i.e. it is a means of entering Paradise).
(b) Sayyiduna Anas (may Allah be pleased with him) said: Allah spoke the truth and al-Hajjaj lied. He used to recite "arjulikum" in the genitive.
(c) Sayyiduna Anas (may Allah be pleased with him) objected only to the reading, not to the washing. Likewise, we have narrated the report of Sayyiduna Anas bin Malik (may Allah be pleased with him) in which the obligation of washing is mentioned.
