I saw Allah's Apostle ﷺ flinging pebbles while riding his camel on the Day of Nahr, and he was saying: Learn your rituals (by seeing me performing them), for I do not know whether I would be performing Hajj after this Hajj of mine.  

أَنَّهُ سَمِعَ جَابِرًا يَقُولُ رَأَيْتُ النَّبِيَّ ﷺ يَرْمِي عَلَى رَاحِلَتِهِ يَوْمَ النَّحْرِ وَيَقُولُ لِتَأْخُذُوا مَنَاسِكَكُمْ فَإِنِّي لاَ أَدْرِي لَعَلِّي لاَ أَحُجُّ بَعْدَ حَجَّتِي هَذِهِ  

I performed Hajj along with Messenger of Allah ﷺ on the occasion of the Farewell Pilgrimage and saw him when he flung pebbles at Jamrat al-'Aqaba and returned while he was riding the camel, and Bilal and Usama were with him. One of them was leading his camel, while the other was raising his cloth over the head of Messenger of Allah ﷺ to protect him from the sun. She (further) said: Messenger of Allah ﷺ said so many things, and I heard him saying: If a slave having some limb of his missing and having dark complexion is appointed to govern you according to the Book of Allah the Exalted. listen to him and obey him.  

سَمِعْتُهَا تَقُولُ حَجَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ حَجَّةَ الْوَدَاعِ فَرَأَيْتُهُ حِينَ رَمَى جَمْرَةَ الْعَقَبَةِ وَانْصَرَفَ وَهُوَ عَلَى رَاحِلَتِهِ وَمَعَهُ بِلاَلٌ وَأُسَامَةُ أَحَدُهُمَا يَقُودُ بِهِ رَاحِلَتَهُ وَالآخَرُ رَافِعٌ ثَوْبَهُ عَلَى رَأْسِ رَسُولِ اللَّهِ ﷺ مِنَ الشَّمْسِ قَالَتْ فَقَالَ رَسُولُ اللَّهِ ﷺ قَوْلاً كَثِيرًا ثُمَّ سَمِعْتُهُ يَقُولُ إِنْ أُمِّرَ عَلَيْكُمْ عَبْدٌ مُجَدَّعٌ حَسِبْتُهَا قَالَتْ أَسْوَدُ يَقُودُكُمْ بِكِتَابِ اللَّهِ تَعَالَى فَاسْمَعُوا لَهُ وَأَطِيعُوا  

I performed Hajj along with Messenger of Allah ﷺ on the occasion of the Farewell Pilgrimage and saw Usama and Bilal (too), one of whom had caught hold of the lose string of the she-camel of Allah's Apostle ﷺ while the other one was raising his cloth (over his head) protecting him from the heat, till he flung pebbles at Jamrat al-'Aqaba.  

حَجَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ حَجَّةَ الْوَدَاعِ فَرَأَيْتُ أُسَامَةَ وَبِلاَلاً وَأَحَدُهُمَا آخِذٌ بِخِطَامِ نَاقَةِ النَّبِيِّ ﷺ وَالآخَرُ رَافِعٌ ثَوْبَهُ يَسْتُرُهُ مِنَ الْحَرِّ حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ قَالَ مُسْلِمٌ وَاسْمُ أَبِي عَبْدِ الرَّحِيمِ خَالِدُ بْنُ أَبِي يَزِيدَ وَهُوَ خَالُ مُحَمَّدِ بْنِ سَلَمَةَ رَوَى عَنْهُ وَكِيعٌ وَحَجَّاجٌ الأَعْوَرُ
