Arabic (Original)
قَالَ حَدَّثَنَا وَكِيعٌ عَنْ إِسْرَائِيلَ عَنْ أَبِي إِسْحَاقَ عَنْ يَحْيَى بْنِ حُصَيْنٍ عَنْ أُمِّهِ قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ 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
He said: Waki' narrated to us, from Isra'il, from Abu Ishaq, from Yahya ibn Husayn, from his mother, who said: I heard the Messenger of God, peace and blessings be upon him, delivering a sermon at the Farewell Pilgrimage, saying: "O people, fear God, and listen and obey, even if an Abyssinian slave with cropped limbs is placed in authority over you, as long as he upholds the Book of God, the Mighty and Majestic, among you."
