African slave trade for centuries. In fact the prophet of Islam himself owned black slaves. It says so right in the Islamic scriptures in the Hadith. Sahih Muslim Book 010, Hadith Number 3901:
Jabir (Allah be pleased with him) reported: There came a slave and pledged allegiance to Allah's Apostle (may peace be upon him) on migration; he (the Holy Prophet) did not know that he was a slave. Then there came his master and demanded him back, whereupon Allah's Apostle (may peace be upon him) said: Sell him to me. And he bought him for two black slaves, and he did not afterwards take allegiance from anyone until he had asked him whether he was a slave (or a free man).
Are black Muslims aware of this? Does those who left Christianity to convert to Islam because they felt Christianity was too much of a white man's religion know that they now swear allegiance to a religion whose founder owned black slaves? Say what you want about Jesus, but he never owned any slaves, certainly not any black ones.
