While you’re at it, you can explain this too. And you could tell us what Muslims did to end slavery:

While most slaves who went to the Americas could marry and have families, most of the male slaves destined for the Middle East were castrated, and most of the children born to the women were killed at birth.
It is estimated that possibly as many as 11 million Africans were transported across the Atlantic (95% of which went to South and Central America, mainly to Portuguese, Spanish and French possessions. Only 5% of the slaves went to the United States).
A comparison of the Muslim slave trade to the American slave trade reveals some interesting contrasts. While two out of every three slaves shipped across the Atlantic were men, the proportions were reversed in the Muslim slave trade. Two women for every man were enslaved by the Muslims.
While the mortality rate for slaves being transported across the Atlantic was as high as 10%, the percentage of slaves dying in transit in the Transsahara and East African slave trade was between 80 and 90%!
While almost all the slaves shipped across the Atlantic were for agricultural work, most of the slaves destined for the Muslim Middle East were for sexual exploitation as concubines, in harems, and for military service.
