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
