Yazid bin Abi Sa'id يزيد بن أبي سعيد النحوي أبو الحسن · Wills (Kitab Al-Wasaya)

The Messenger of Allah (ﷺ) said to me: Abu Dharr, I see you weak, and I like for you what I like for myself. Do not be a leader of two (persons), and do not be a guardian of an orphan. Abu Dawud said: This has been narrated only by the people of Egypt.
