It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever washes the deceased should take a ritual bath (ghusl), and whoever carries him should perform ablution (wudu)." (b) This Amr bin Umayr is known only through this hadith, and he is not well-known.
