Sahih Muslim, 4103

Jabir (Allah be pleased with him) reported:My camel had grown tired as Allah's Messenger (ﷺ) came to me. He goaded it and it began to jump. After that I tried to restrain its rein so that I could listen to his (Prophet's) words, but I could not do that. Allah's Apostle (ﷺ) met me and said: Sell it to me, and I sold it for five 'uqiyas.

When I came to Medina I handed over that to him and he made an addition of an uqiya (to that amount which had been agreed upon) and then presented that (camel) to me

Il a dit : « D’accord, tu peux l’utiliser jusqu’à Médine. » Quand je suis arrivé à Médine, je le lui ai remis et il a ajouté une ‘uqiya au montant convenu, puis il m’a offert le chameau
