Musnad Abu Ya'la al-Mawsili 108:198

Zakariya narrated to us, Hushaym narrated to us, Sayyar informed us, from Abu Hubayrah al-Ansari, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) bought a camel from me that I owned while we were on a journey. He granted me its back [to ride] until we arrived. When we arrived, I came to him with the camel and handed it over to him. He ordered that I be given two *uqiyahs* as its price. I departed, and suddenly his messenger followed me and said, "Come, the Prophet (peace and blessings of Allah be upon him) is calling you." I thought that he had changed his mind. When I came to him, he said to me, "Take your camel, for it is yours." I departed and met a man from the Jews and informed him of what had happened. He began to marvel and said, "He gave you the price and returned the camel to you?"
