“Even if the one appointed over you is a mutilated Ethiopian slave whose nose and ears have been cut off, listen to him and obey, so long as he leads you according to the Book of Allah.” (Using translation from Ibn Mājah 2861)
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ وَهُوَ وَاقِفٌ بِعَرَفَةَ إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ فَاسْمَعُوا لَهُ وَأَطِيعُوا مَا قَادَكُمْ بِكِتَابِ اللهِ تَعَالَى
