From Sahih Muslim (Hadith 3139):
Umm al-Husain (Allah be pleased with her) reported:I performed Hajj along with Allah's Messenger (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
