Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
Racism whether upon open or hidden, is an evil aspect of life which Islams seeks to eradicate. It is clear from the versus of the Quran, the book of the muslims, and many sayings of our final prophet which have narrated by his companions, that differences in colour, tribes, races, or traditions are not to be excuses for unjust behaviour or treatment.
Allah Ta'ala says,
"O Mankind! Most certainly, it is We (God almighty) who have Created you all From a single (pair) Of a male and a female, And it is we who Have made you into Nations and tribes, That you may recognise each other (Not that you may despise each other). Verily, the noblest of you In the sight of Allah Is (he who is) the most Righteous of you." (49:13)
"And mankind is naught but a single nation." (2:213)
"And among His Signs Is the creation of the heavens And the earth, and the variations In your languages And your colours; verily In that are Signs For those who know." (30:22)
Prophet (Sallallahu Alaihi Wasallam) said, ""All men (includes women) are equal in Islam, the Arab has no superiority over the non-Arab, nor does the non-Arab have superiority over the Arab, save in the fear of God."
