Religious doctrines are instituted by men, no matter how perfect will be subject to human error.. I find that whole Europe abolishing and fighting to abolish elsewhere kind of funny.. I think there are multiple forms of subjugation, slavery and racism, not letting a scarved school girl on a bus is certainly one of them. So I'd really let go of that if you wanted to let your case have some credence.
Slavery was never a 'color' race thing in Islam.. as evidenced:
“And We have not sent you (O Muhammad) except as a bearer of glad tidings and a Warner to all mankind, but most of people know not.” (Quran 34:28)
Bilal the Abyssinian
One of the first to accept Islam was an Abyssinian slave named Bilal. Traditionally, black Africans were a lowly people in the sight of Arabs who thought them to be of little use beyond entertainment and slavery. When Bilal embraced Islam, his pagan master had him brutally tortured in the scorching desert heat until Abu Bakr, the Prophet’s closest friend, rescued him by buying his freedom.
The Prophet appointed Bilal to call the believers to prayer. The
athan heard from minarets in every corner of the world since, echoes the exact same words recited by Bilal. Thus, a onetime lowly slave won a unique honor as Islam’s first muezzin.
“And indeed We have honored the Children of Adam...” (Quran 17:70)
Western romantics hail ancient Greece as being the birthplace of democracy.
[4] The reality was that, as slaves and women, the vast majority of Athenians were denied the right to elect their rulers. Yet, Islam ordained that a slave could himself be ruler! The Prophet ordered:
“Obey your ruler even if he be an Abyssinian slave.” (
Ahmad)
all the best
