Al-Adab Al-Mufrad #598

Abu Hurayra said, "A man from the Banu Fazara gave a camel tot he Prophet, may Allah bless him and grant him peace, and he gave him something in exchange for it. That angered the man and I heard the Prophet, may Allah bless him and grant him peace, state on the minbar, 'One of you gives a gift and when I give him something in exchange he becomes angry. By Allah, after this year, I will never accept a gift from any Arab except for Quraysh, the Ansar, a Thaqifi or a Dawsi!'"
