They gave the nigga an insignificant token job and he was still called a by other as7aab like Abu Dhar Al Ghifari.
Even the 'noble' Sahaaba hated negroes
Don't lie, Abu Dhar was reprimanded for that. Besides, you're judging people who were raised in the Pre-Islamic period aka jahiliyya.
“Abu Dharr, the leader of the tribe of Ghifar, and one who accepted Islam in its early days, narrates:
Once I was conversing with Bilal. Our conversation gave way to a dispute. Angry with him, the following insult burst from my mouth: 'You cannot comprehend this, O son of a black woman!'
As Islam expressly forbade all kinds of racial, tribal and color discrimination, Bilal was both upset and greatly angered.
Some time later, a man came and told me that the Messenger of God, upon him be peace and blessings, summoned me. I went to him immediately. He said to me:
'I have been informed that you addressed Bilal as the son of a black woman.'
I was deeply ashamed and could say nothing. God's Messenger continued his reprimand: 'This means you still retain the standards and judgements of the pre-Islamic days of ignorance. Islam has eradicated all those false standards or measures judging people by blood, fame, color or wealth. It has established that the best and most honorable of men is he who is the most pious and upright in conduct. Is it right to defame a believer just because he is black?'
Abu Dharr felt profound remorse. He went straight to Bilal's house and, putting his head on the threshold, said: 'This head will not rise from here until the blessed feet of Bilal tread on the face of foolish, impolite Abu Dharr.'
Bilal responded: 'That face deserves to be kissed, not trodden upon,' and forgave Abu Dharr.”
So one set of rules for Arabs and another for everybody else
They fought, persecuted, and killed tons of Muslims, but forgiven in an afternoon
I want to know who the Bantus were beefing with when their men, women, and children were being hauled off by the millions
Not at all. That was a special case and it was actually a decision that has benefited Islam and the Muslims greatly. The Arabs who were enslaved during the emergence of Musaylama and other similar occasions were not freed.
