"The Messenger of Allah said to me: 'O Abu Dharr, I think that you are weak, and I like for you what I like for myself. Do not accept a position of Amir over two people, and do not agree to be the guardian of an orphan's property.'" (Using translation from Nasāʾī 3667)  

قَالَ لِي رَسُولُ اللهِ ﷺ يَا أَبَا ذَرٍّ إِنِّي أَرَاكَ ضَعِيفًا وَإِنِّي أُحِبُّ لَكَ مَا أُحِبُّهُ لِنَفْسِي لَا تَأَمَّرَنَّ عَلَى اثْنَيْنِ وَلَا تَوَلَّيَنَّ عَلَى مَالِ يَتِيمٍ
