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.  

لِي رَسُولُ اللَّهِ ﷺ يَا أَبَا ذَرٍّ إِنِّي أَرَاكَ ضَعِيفًا وَإِنِّي أُحِبُّ لَكَ مَا أُحِبُّ لِنَفْسِي فَلاَ تَأَمَّرَنَّ عَلَى اثْنَيْنِ وَلاَ تَوَلَّيَنَّ مَالَ يَتِيمٍ
