Musnad Ahmad 30:800

Yazid narrated to us, Abu Ma'shar informed us, from Sa'id ibn Abi Sa'id al-Maqburi, from Abu Hurairah: That a Bedouin gifted a young she-camel to the Messenger of Allah, may Allah bless him and grant him peace, so he compensated him with six young she-camels for it. He became displeased with it, and that reached the Prophet, may Allah bless him and grant him peace. He praised Allah and extolled Him, then said: "Indeed, so-and-so gifted me a she-camel, and it is my she-camel; I recognize it as I recognize some of my own family. It went away from me on the day of Zaghabat, so I compensated him with six young she-camels, yet he remained displeased. I have indeed intended not to accept a gift except from a Qurayshi, or an Ansari, or a Thaqafi, or a Dawsi."
