Arabic (Original)
حَدَّثَنَا أَبُو نُعَيْمٍ قَالَ حَدَّثَنَا يُونُسُ عَنْ الْعَيْزَارِ بْنِ حُرَيْثٍ قَالَ سَمِعْتُ أُمَّ الْحُصَيْنِ الْأَحْمَسِيَّةَ قَالَتْ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي حَجَّةِ الْوَدَاعِ عَلَيْهِ بُرْدٌ قَدْ الْتَفَعَ بِهِ مِنْ تَحْتِ إِبْطِهِ فَأَنَا أَنْظُرُ إِلَى عَضَلَةِ عَضُدِهِ تَرْتَجُّ وَهُوَ يَقُولُ يَا أَيُّهَا النَّاسُ اتَّقُوا اللَّهَ وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ فَاسْمَعُوا وَأَطِيعُوا مَا أَقَامَ فِيكُمْ كِتَابَ اللَّهِ.

Abu Nu'aym told us, he said: Yunus told us, from al-Ayzar ibn Hurayth, he said: I heard Umm al-Husayn al-Ahmasiyyah say: I saw the Messenger of Allah (peace and blessings be upon him) during the Farewell Pilgrimage wearing a cloak which he had wrapped around himself from under his armpit, and I was looking at the muscle of his upper arm quivering, and he was saying: "O people, fear Allah and obey, even if a mutilated Abyssinian slave is placed in authority over you; listen and obey so long as he maintains among you the Book of Allah."
