Superiority of race or segregation is not only eliminated and void in the eyes of Islam, but the equality of man is an absolute reality from the point of view of Islam, and it says that all men are equal, all are from one father and one mother and are members of one family, and from the aspect of nobility, origin and connections they are equal partners. no one is better than anyone else, except in purity and devoutness.
"O mankind, we have created you male and female, and appointed you races and tribes that you may know one another. surely the noblest among you in the sight of Allah is the most godfearing of you; Allah is All-knowing All-aware." (XLiX:13)
