“Generation after generation was destroyed by wars because a man would
seek the aid of his tribe, even if he was upon falsehood and the likes
of that from trivial causes and despicable motives.
So Islam came to erase all of these loathsome outward practices in their
lives when it made them equal with regards to the rights, and it made
their slogans of allegiance to, “al-Islam.” And Islam made them excel
over one another due to taqwa; (righteousness) and obedience to Allah.
So there is no excellence for an Arab over a non-Arab, nor is there any
excellence for a non-Arab, over an Arab or for a white person over a
black one, or for a black person over a white one, except due to taqwa.”
- From the introduction of Shaykh 'Abd al-Salam Ibn Burjis
