Musannaf Ibn Abi Shayba 27:114

Muhammad ibn Ubayd narrated to us, from al-A’mash, from Salim ibn Abi al-Ja’d, from Jabir ibn Abdullah, who said: The Messenger of Allah (may Allah bless him and grant him peace) passed by me while I was driving a camel of mine, and I was at the back of the people, and it was limping or had become ill. He said: "What is the matter with it?" I said: "O Messenger of Allah, it is limping or has become ill." So he took something that was in his hand and struck it, then said: "Mount it." And I had been holding it back so that they could catch up with me.
