Sunan an-Nasa'i 4640
It was narrated tat Jabir Said:
"The Messenger of Allah caught up with me when I was riding a bad camel of ours, and I said: 'We have a bad camel, mare's the pit! The Prophet said: Will you sell it to me, O Jabir?' I Said, 'No, It is yours, O Messenger of Allah.; He said: 'O Allah forgive him; O Allah, have mercy on him. I will buy it for such and such, and I will lend it to you to ride until (we reach) al-Madinah.' When Reached al-Madinah, I prepared it, and brought it to him, and he said: O Bilal, give him its price,' When I turned to leave, he called me back, and I was afraid that he would give it back at he said: 'It is yours.
