"They [the Shu`ubiyya] maintain that eloquence is prized by all people at all times -- even the Zanj, despite their dimness, their boundless stupidity, their obtuseness, their crude perceptions and their evil dispositions, make long speeches." Jahiz, Al-Bayan wa`l-tabyin, vol. 3

"The Zanj are so uncivilized that they have no notion of a natural death. If a man dies a natural death, they think he was poisoned. Every death is suspicious with them, if a man has not been killed by a weapon." Abu Rayhan al-Biruni, India, 1030 AD
About the Zanj: "Their nature is that of wild animals. They are extremely black." About the Sudan: "Among themselves there are people who steal each other's children and sell them to the merchants when the latter arrive." Hudud al-`Alam, 982 AD
"If (all types of men) are taken, from the first, and one placed after another, like the Negro from Zanzibar, in the Southern-most countries, the Negro does not differ from an animal in anything except the fact that his hands have been lifted from the earth,--in no other peculiarity or property,--except for what God wished. Many have seen that the ape is more capable of being trained than the Negro, and more intelligent." Philosopher-theologian Nasir al-Din Tusi (1201-74), Tasawwurat
"Therefore, the Negro nation are, as a rule, submissive to slavery, because [Negroes] have little [that is essentially] human and have attributes that are quite similar to those of dumb animals, as we have stated." Ibn Khaldun, Muqaddimah, 14th century AD
