Allah (SWT) says "O Mankind! We have created you from a male and female, and made you into nations and tribes, that you may know one another. Verily, the most honorable of you in the sight of Allah is he who has most Taqwa among of you. Verily, Allah is All-Knowing, All-Aware." (Qur'an 49:13)
Allah's Messenger (S) eradicated the problem of racial or colour discrimination by saying:"There is no superiority of an Arab over a non-Arab, nor of a non-Arab over an Arab or white person over a black person or a black person over white person except through piety. Verily the most honored of you is the most righteous."
(Musnad Ahmad)
In surah Al-Room Allah (SWT) says, "And one of His signs is the creation of the heavens and the earth and the diversity of your languages and colors; most surely there are signs in this for men of sound knowledge." (Qur'an 30:22)
With this verse, Islam declares equality among people as one human race. All praise and thanks be to Allah, the Only True God!
