Scientifically, there are four human races.. all of them are humans, with some differences even in their blood.
Your insisting on one human race indicates your narrow mind.
The evolutionist among the white race insult the other human races specially the black race, by claiming humanity originated in Africa, and so the other races will be superior to the black according to their claim.
While the truth is opposite to this.
Each human race originated in one continent separated from the other continents.. in the past it made far far and very far distances.
Anyhow, there had been of intermingling of these races by intermarriages: daughters to the sons of other races and vice versa.
It can't be (God's jealousy and zealously) does not permit this that the brother marries the sister, but only according to corrupt atheist minds.
But because the white race is the last created one, it has been better in shape and in some other criteria.. God always creates better and better and better...while the other 3 races have also their specific criteria ..
Muslims all over the world belong to all races may be.
The important thing is the piety, righteousness, fearing of God and the devotion to God alone... and it is not the color or the beauty which lets man go to Paradise and receive the good pleasure of God.
