The Messenger of Allah ﷺ departed from Arafah with Usama bin Zayd riding behind him. His she-camel grew restless beneath him while he was raising his hands, though they did not pass above his head, and he proceeded at a steady pace until he reached Jam. The following day he departed again with Fadl bin Abbas riding behind him, and he continued reciting the talbiyah until he cast the pebbles at Jamrat al-Aqaba.
حدثنا يحيى بن سعيد عن عبد الملك حدثنا عطاء
أفاض رسول الله ﷺ من عرفة وردفه أسامة بن زيد فجالت به الناقة وهو رافع يديه لا يجاوزان رأسه فسار على هينته حتى أتى جمعا ثم أفاض الغد وردفه الفضل بن عباس فما زال يلبي حتى رمى جمرة العقبة
Its isnad is sahih. It has already come with a similar wording in the Musnad of Fadl bin Abbas, from Abdullah bin Abbas, from him, no. 1816. See also 1860."On his form" (على هيئته). In H it reads "on its form" (على هيئته), and the correct reading is what we have adopted.
