Arabic (Original)
حَدَّثَنَا وَكِيعٌ قَالَ شُعْبَةُ أَتَيْتُ يَحْيَى بْنَ الْحُصَيْنِ فَسَأَلْتُهُ فَقَالَ حَدَّثَتْنِي جَدَّتِي قَالَتْ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ وَهُوَ وَاقِفٌ بِعَرَفَةَ إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ فَاسْمَعُوا لَهُ وَأَطِيعُوا مَا قَادَكُمْ بِكِتَابِ اللَّهِ تَعَالَى.
English Translation
Waki' told us, he said: Shu'bah [said]: I came to Yahya ibn al-Husayn and asked him, and he said: My grandmother told me, she said: I heard the Prophet (peace and blessings be upon him) say, while standing at Arafah: "If a mutilated Abyssinian slave is placed in authority over you, then listen to him and obey, so long as he leads you by the Book of Allah, the Exalted."
