I heard her say: I performed Hajjat-ul-Wada' in the company of the Messenger of Allah ﷺ. He said a lot of things (on this occasion). Then I heard him say: If a maimed slave is appointed a commander over you the narrator says: I think she said:" a black stave" who leads you according to the Book of Allah, then listen to him and obey him.  

سَمِعْتُهَا تَقُولُ حَجَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ حَجَّةَ الْوَدَاعِ قَالَتْ فَقَالَ رَسُولُ اللَّهِ ﷺ قَوْلاً كَثِيرًا ثُمَّ سَمِعْتُهُ يَقُولُ إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ مُجَدَّعٌ حَسِبْتُهَا قَالَتْ أَسْوَدُ يَقُودُكُمْ بِكِتَابِ اللَّهِ فَاسْمَعُوا لَهُ وَأَطِيعُوا  

[Machine] I performed the farewell pilgrimage with the Messenger of Allah ﷺ, and I saw either Usama or Bilal leading the Messenger of Allah's camel by its reins, and the other one raising his garment to cover him from the heat until he threw the pebbles at Al-Aqaba. Then he turned and the people stood up. He placed his garment from under his right armpit on his left shoulder. I saw beneath his right sleeve a patch resembling a collection [of lice]. Then he mentioned many things, and he used to say, ﷺ, "If a slave who is a Muja'adh comes to you with the Book of Allah, listen and obey. Have I conveyed (the message)?"  

حَجَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ حَجَّةَ الْوَدَاعِ فَرَأَيْتُ أُسَامَةَ أَوْ بِلَالًا يَقُودُ بِخِطَامِ نَاقَةِ رَسُولِ اللَّهِ ﷺ وَالْآخَرَ رَافِعُ ثَوْبَهُ يَسْتُرُهُ بِهِ مِنَ الْحَرِّ حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ ثُمَّ انْصَرَفَ فَوَقَفَ النَّاسُ وَقَدْ جَعَلَ ثَوْبَهُ مِنْ تَحْتِ إِبْطِهِ الْأَيْمَنِ عَلَى عَاتِقِهِ الْأَيْسَرِ قَالَ فَرَأَيْتُ تَحْتَ غُضْرُوفِهِ الْأَيْمَنِ كَهَيْئَةِ جُمْعٍ ثُمَّ ذَكَرَ قَوْلًا كَثِيرًا وَكَانَ فِيمَا يَقُولُ ﷺ «إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ مُجَدَّعٌ أَسْوَدُ يَقُودُكُمْ بِكِتَابِ اللَّهِ فَاسْمَعُوا وَأَطِيعُوا» ثُمَّ قَالَ «هَلْ بَلَّغْتُ؟ »  

[Machine] I performed Hajj with the Messenger of Allah ﷺ during the Farewell Hajj. I saw Bilal and Usama, with Bilal leading his mount by the reins and the other raising his garment as a shield against the heat until he threw the jamarat Al-Aqaba (pebbles at the Devil). Then he turned around, placing his garment under his right armpit and over his left shoulder. I saw on the underside of his right shoulder a mark resembling the shape of a bracelet. He stood among the people and delivered a long speech, part of which was that "I have appointed a black Abyssinian named Bilal as leader over you. He will lead you with the Book of Allah, so listen to him and obey him."  

حَجَجْتُ مَعَ رَسُولِ اللهِ ﷺ حَجَّةَ الْوَدَاعِ فَرَأَيْتُ بِلَالًا وَأُسَامَةَ وَبِلَالٌ يَقُودُ بِخِطَامِ رَاحِلَتِهِ وَالآخَرُ رَافِعًا ثَوْبَهُ سُتْرَةً بِهِ مِنَ الْحَرِّ حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ ثُمَّ انْصَرَفَ وَقَدْ جَعَلَ ثَوْبَهُ تَحْتَ إِبْطِهِ الْأَيْمَنِ عَلَى عَاتِقِهِ الْأَيْسَرِ فَرَأَيْتُ تَحْتَ عُرْصُوفِ كَتِفِهِ الْأَيْمَنِ كَهَيْأَةِ جَمْعٍ فَوَقَفَ لِلنَّاسِ فَقَالَ قَوْلًا كَثِيرًا فَكَانَ مِمَّا يَقُولُ إِنْ «أُمِّرَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ أَسْوَدُ يَقُودُكُمْ بِكِتَابِ اللهِ فَاسْمَعُوا وَأَطِيعُوا»  

[Machine] I heard her say that she performed the farewell Hajj with the Messenger of Allah ﷺ . I saw him when he stoned the Jamarat al-Aqaba and then departed while he was on his mount, accompanied by Bilal and Osama. One of them led his mount while the other held up his garment above the head of the Messenger of Allah ﷺ to shield him from the sun.  

سَمِعْتُهَا تَقُولُ حَجَجْتُ مَعَ رَسُولِ اللهِ ﷺ حَجَّةَ الْوَدَاعِ فَرَأَيْتُهُ حِينَ رَمَى جَمْرَةَ الْعَقَبَةِ وَانْصَرَفَ وَهُوَ عَلَى رَاحِلَتِهِ وَمَعَهُ بِلَالٌ وَأُسَامَةُ أَحَدُهُمَا يَقُودُ بِهِ رَاحِلَتَهُ وَالْآخَرُ رَافِعٌ ثَوْبَهُ عَلَى رَأْسِ رَسُولِ اللهِ ﷺ مِنَ الشَّمْسِ  

"عَنْ أُمِّ حُصَيْنٍ قَالَتْ: حَجَجْتُ مَعَ رَسُولِ اللهِ ﷺ حَجَّةَ الْوَدَاعِ، فَرَأَيْتُ أُسَامَةَ وَبِلَالًا يَقُودُ بِخطامِ رَاحِلَةِ رَسُولِ اللهِ ﷺ وَالآخَر رَافِعٌ ثوْبَهُ يَسْتُرُ بِهِ مِنَ الْحَرِّ حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ ثُمَّ انْصَرَفَ، فَوَقَفَ النَّاسُ وَقَدْ جَعَلَ ثَوْبَهُ تَحْتَ إِبْطِهِ عَلَى عَاتِقِهِ الأَيْسَرِ، فَرَأيْتُ عِنْدَ غُضْرُوفِهِ الأَيْمَنِ كَهَيْئَةِ جَمْعٍ ثُمَّ ذكَرَ قَوْلًا كَثِيرًا، ثُمَّ قَالَ: اللَّهُمَّ اشْهَدْ هَلْ بَلَّغْتُ؟ وَكَانَ فِيمَا يَقُولُ: إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ مُجَدَّعٌ أَسْوَدُ يَقُودُكُمْ بِكِتَابِ اللهِ - تَعَالَى- فَاسْمَعُوا وَأَطِيعُوا".
