وَعَنْ أُمِّ الْحُصَيْنِ قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ مُجَدَّعٌ يَقُودُكُمْ بِكِتَابِ اللَّهِ فَاسْمَعُوا لَهُ وَأَطيعُوا» . رَوَاهُ مُسلم

Umm al-Husain reported God’s Messenger as saying, “If a slave who has been mutilated is made your commander and leads you in accordance with God’s Book, listen to him and obey.” Muslim transmitted it.
