Oneness of Mankind:
People are created equal in front of the Law of God. There is no superiority for one race over another. God made us of different colors, nationalities, languages and beliefs so as to test who is going to be better than others. No one can claim that he is better than others. It is only God Who knows who is better. It depends on piety and righteousness.
The Quran says: "O Mankind! We created you from a single pair of male and female, and made you into nations and tribes that ye may know each other. Verily, the most honored of you in the sight of God is the most righteous of you." (49.13)
In his sermon of fare well pilgrimage the Prophet Muhammad (Peace be upon him) said: 'O People! You are all children of Adam and he was created with the dust. Arabs and non-Arabs, Blacks and Whites all are equal. Nobody has superiority over other except by piety and good actions.'
