Bukhari 4.52.137:
"The Prophet said, 'Let the negro slave of Dinar perish. And if he is pierced with a thorn, let him not find anyone to take it out for him.... If he [the black slave] asks for anything it shall not be granted, and if he needs intercession [to get into paradise], his intercession will be denied.'"
Slavery, raping slave girls, owning slaves, selling boys and women as trophies of war, sharing the booty (including slaves) obtained in raids and wars with Allah are all central teachings of Islam. Slavery was one of the major driving forces behind the expansion of Islam. After assuming his prophetic career, Prophet Muhammad enslaved large number of men and women, owned dozens of slaves, he sold many slaves as well as used the female captives as sex-slaves on top his dozen wives. Islam is such as vile, evil cult, which has been embraced by todays civilized worlds 1.2 billion people as the perfect guide to life and its Prophet as perfect human being, the greatest apostle of God, a man of peace.
