Sa'id narrated it with the same chain in the same way, and added: "the red camels and their black ones." Sayyiduna Ali (may Allah be pleased with him), whenever he washed a deceased person, would take a ritual bath.
Al-Hasan bin Yazid al-Asamm is alone in narrating it with this chain. Ibn Adi said: Al-Hasan bin Yazid al-Kufi is not strong, and his narration from al-Suddi is not preserved; this well-known hadith revolves around Abu Ishaq al-Sabi'i from Najiyah bin Ka'b from Ali.
