Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that black people were mentioned in the presence of the Prophet (peace and blessings be upon him), so he (peace and blessings be upon him) said: "Leave me out of the matter of the black people; the black man is only a slave to his belly and his private parts."
