Abbad bin Abdullah bin al-Zubayr (may Allah have mercy on him) says: I heard Sayyidah Aishah (may Allah be pleased with her) saying, and he narrated the whole hadith, except that he said: They washed him (peace and blessings be upon him) while a shirt was on him (peace and blessings be upon him); they poured water over the shirt and rubbed the body with the shirt itself, without their hands.
