Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَنْ إِسْرَائِيلَ عَنْ أَبِي إِسْحَاقَ عَنْ يَحْيَى بْنِ الْحُصَيْنِ عَنْ أُمِّهِ قَالَتْ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَخْطُبُ فِي حَجَّةِ الْوَدَاعِ يَقُولُ يَا أَيُّهَا النَّاسُ اتَّقُوا اللَّهَ وَاسْمَعُوا وَأَطِيعُوا وَإِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ مُجَدَّعٌ مَا أَقَامَ فِيكُمْ كِتَابَ اللَّهِ عَزَّ وَجَلَّ.
English Translation
Waki' told us, from Isra'il, from Abu Ishaq, from Yahya b. al-Husayn, from his mother, she said: I heard the Prophet (peace and blessings be upon him) delivering a sermon at the Farewell Pilgrimage, saying: "O people, fear God, listen and obey, even if a mutilated Abyssinian slave is put in authority over you, so long as he upholds among you the Book of God, Mighty and Majestic."
