“All mankind is from Adam and Eve, an Arab has no superiority over a non-Arab nor a non-Arab has any superiority over an Arab; also a white has no superiority over black nor a black has any superiority over white except by piety (taqwa) and good action.”
(Bukhari)
Islam rejects certain individuals or nations being favoured because of their wealth, power, or race. God created human beings as equals who are to be distinguished from each other only on the basis of their faith and piety.
One of the major problems facing mankind today is social inequality. The developed world can send a man to the moon but cannot stop man from hating and fighting his fellow beings. Ever since the days of the Prophet Muhammad (peace and blessings of Allah be to him), Islam has provided a vivid example of how racism can be brought to an end. Hajj, the annual pilgrimage to Makkah, shows the real Islamic brotherhood of all races and nations, when about two million Muslims from all over the world come to Makkah to perform the pilgrimage.
In another hadith, the Prophet has said: “You are all the children of Adam, and Adam was created from the dust. Let the people give up boasting of their ancestors, otherwise they will stand more degraded than a mean insect in the sight of Allah.”
In yet another hadīth he said: “Allah will not enquire about your lineage on the Day of Resurrection. The most honourable in the sight of Allah is he who is most pious.”
