If a slave is appointed over you and he conducts your affairs according to the Book of Allah, you should listen to him and obeey (his orders).  

أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ وَهُوَ يَقُولُ وَلَوِ اسْتُعْمِلَ عَلَيْكُمْ عَبْدٌ يَقُودُكُمْ بِكِتَابِ اللَّهِ فَاسْمَعُوا لَهُ وَأَطِيعُوا  

I heard the Messenger of Allah ﷺ delivering Khutbah during the farewell Hajj, and he was wearing a Burd which he had wrapped from under his armpit." She said: "I was look at muscle of his upper arm quivering and I heard him saying: O you people! Have Taqwa of Allah. If a mutilated Ethiopian slave is put in command over you, then listen to him and obey him, as long as he upholds the Book of Allah among you.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ وَعَلَيْهِ بُرْدٌ قَدِ الْتَفَعَ بِهِ مِنْ تَحْتِ إِبْطِهِ قَالَتْ فَأَنَا أَنْظُرُ إِلَى عَضَلَةِ عَضُدِهِ تَرْتَجُّ سَمِعْتُهُ يَقُولُ يَا أَيُّهَا النَّاسُ اتَّقُوا اللَّهَ وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَاسْمَعُوا لَهُ وَأَطِيعُوا مَا أَقَامَ لَكُمْ كِتَابَ اللَّهِ  

“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.”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَاسْمَعُوا لَهُ وَأَطِيعُوا مَا قَادَكُمْ بِكِتَابِ اللَّهِ  

[Machine] I heard the Messenger of Allah ﷺ delivering a sermon during the Farewell Pilgrimage, saying, "O people! Fear Allah and listen and obey, even if a slave from Abyssinia is appointed as your leader, as long as he establishes the Book of Allah among you."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ يَقُولُ يَا أَيُّهَا النَّاسُ اتَّقُوا اللهَ وَاسْمَعُوا وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ مَا أَقَامَ فِيكُمْ كِتَابَ اللهِ ﷻ  

[Machine] I heard the Prophet ﷺ giving a sermon at Arafat during the Farewell Pilgrimage, saying, "O people, fear Allah and listen and obey, even if an Abyssinian slave is appointed as your leader, for indeed whoever among you lives [after me] will see much strife. So hold fast to my Sunnah and the Sunnah of the rightly guided caliphs after me. Adhere to it and cling to it tightly. And beware of newly invented matters [in religion], for every innovation is misguidance."  

سَمِعْتُ النَّبِيَّ ﷺ بِعَرَفَاتٍ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ يَقُولُ يَا أَيُّهَا النَّاسُ اتَّقُوا اللهَ وَاسْمَعُوا وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ مَا أَقَامَ فِيكُمْ كِتَابَ اللهِ ﷻ  

If a slave is appointed over you and he conducts your affairs according to the Book of Allah, you should listen to him and obeey (his orders). (Using translation from Muslim 1838a)  

أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ يَقُولُ لَوْ اسْتُعْمِلَ عَلَيْكُمْ عَبْدٌ يَقُودُكُمْ بِكِتَابِ اللهِ ﷻ فَاسْمَعُوا لَهُ وَأَطِيعُوا  

[Machine] I heard the Prophet ﷺ while he was standing at Arafat with a cloak wrapped around him, saying, "Listen and obey, even if you are ruled by an Ethiopian slave. Indeed, as long as he establishes amongst you the Book of Allah..."  

سَمِعْتُ النَّبِيَّ ﷺ وَهُوَ وَاقِفٌ بِعَرَفَةَ وَعَلَيْهِ بُرْدَةٌ قَدِ الْتَفَعَ بِهَا وَهُوَ يَقُولُ اسْمَعُوا وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مَا أَقَامَ فِيكُمْ كِتَابَ اللهِ  

[Machine] I saw the Messenger of Allah ﷺ delivering a sermon in Mina. He had wrapped his garment around him, and a muscle in his arm was twitching as he said, "O people, fear Allah and listen and obey, even if a slave from Abyssinia were made your leader. Listen and obey as long as he establishes among you the Book of Allah, the Exalted."  

أَنَا رَأَيْتُ رَسُولَ اللهِ ﷺ يَخْطُبُ بِمِنًى قَدِ الْتَحَفَ بِثَوْبِهِ وَإِنَّ عَضَلَةَ عَضُدِهِ تَرْتَجُّ وَهُوَ يَقُولُ «يَا أَيُّهَا النَّاسُ اتَّقُوا اللهَ وَاسْمَعُوا وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَاسْمَعُوا وَأَطِيعُوا مَا أَقَامَ فِيكُمْ كِتَابَ اللهِ تَعَالَى»  

[Machine] I saw the Messenger of Allah ﷺ during the Farewell Hajj and I heard him reminding and commanding them. From what I heard him say, he said, "A black servant will be assigned to you from Abyssinia. He will recite the Book of Allah to you, so listen to him and obey him."  

رَأَيْتُ رَسُولَ اللهِ ﷺ فِي حَجَّةِ الْوَدَاعِ وَسَمِعْتُهُ يُذَكِّرُهُمْ وَيَأْمُرُهُمْ وَكَانَ فِيمَا سَمِعْتُهُ يَقُولُ إِنِ «اسْتُعْمِلَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَأَقَامَ فِيكُمْ كِتَابَ اللهِ فَاسْمَعُوا لَهُ وَأَطِيعُوا»  

[Machine] I heard the Prophet, ﷺ , while he was wearing a cloak and he said, "There has been appointed upon you a servant from Abyssinia who is a caller (to prayer), so listen to him and obey him with regards to the Book of Allah, the Most High."  

سَمِعْتُ النَّبِيَّ ﷺ وَعَلَيْهِ بُرْدَهُ مُتَلَفِّعٌ بِهَا وَهُوَ يَقُولُ إِنْ «أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَاسْمَعُوا لَهُ مَا أَقَامَ فِيكُمْ كِتَابَ اللهِ تَعَالَى»  

"يَا أَيُّهَا النَّاسُ: اتَّقُوا (الله) (*) وإنْ أُمِّرَ عَلَيْكُمْ عَبدٌ حَبَشِىٌّ مُجَدَّعٌ فَاسْمَعُوا لَهُ وَأَطِيعُوا مَا أَقَامَ لَكُمْ (كِتَابَ اللهِ) ".
