Umm al-Husain (Allah be pleased with her) reported:
I performed Hajj along with Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ) while the other one was raising his cloth (over his head) protecting him from the heat, till he flung pebbles at Jamrat al-'Aqaba.
