It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When you wash one of your deceased, a ritual bath (ghusl) is not obligatory upon you, for your deceased is not impure; rather, it is sufficient for you to wash your hands." This hadith is sahih (authentic) on the condition of Imam Bukhari, but the two Shaykhs did not record it. It contains a refutation of the disputed hadith narrated from Muhammad bin Amr, in whose various chains it is stated: "Whoever washes a deceased person should take a ritual bath himself."
