I performed the Farewell Pilgrimage with the Messenger of Allah ﷺ. I saw Usama and Bilal, one of them holding the halter of the Prophet's ﷺ she-camel, and the other raising his garment to shield him from the heat, until he cast the pebbles at Jamrat al-Uqba.
حججت مع رسول الله ﷺ حجة الوداع، فرأيت أسامة وبلالا، وأحدهما آخذ بخطام ناقة النبي ﷺ، والآخر رافع ثوبه يستره من الحر حتى رمى جمرة العقبة.
