A Question on Racism

Q. Please share with me Qur'an and Hadith verses and authoritative Islamic Commentary on Race/Racism, etc. (via .pdf or otherwise) demarcative of the limit beyond which The Deity requires absolutely no thought or action greater than mere disagreement with the clearest of wrongdoing in one's own heart.

A. From the Qur'an:

"And among His Signs is the creation of the heavens and the earth, and the variations in your languages and your colors: verily in that are Signs for those who know." (30:22)

"O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honored of you in the sight of God is (he who is) the most righteous of you. And God has full knowledge and is well acquainted (with all things)." (49:13)

From the hadith:

"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 a black nor a black has any superiority over a white - except by piety and good action. Learn that every Muslim is a brother to every Muslim and that the Muslims constitute one brotherhood. Nothing shall be legitimate to a Muslim which belongs to a fellow Muslim unless it was given freely and willingly. Do not therefore do injustice to yourselves. Remember one day you will meet Allah and answer your deeds. So beware: do not stray from the path of righteousness after I am gone." Farewell Pilgrimage Sermon

"Whosoever of you sees wrongdoing, let him change it with his hand; and if he is not able to do so [i.e., lacks the power], then [let criticize it] with his tongue; and if he is not able to do so, then [detest it in] his heart — and that is the weakest of faith.” [Muslim]
