Hadith 6:846
'Abd al-A'la narrated to us, from Ma'mar, from al-Zuhri, from Sa'id, that the one who took charge of the burial of the Prophet, may Allah bless him and grant him peace, and his shrouds, were four people, excluding the [other] people: 'Ali, al-'Abbas, al-Fadl, and Salih, the freed slave of the Prophet, may Allah bless him and grant him peace.
