An example of Sunnism’s racism against non-Arab Muslims is in Shafi’i classical fiqh manual, “Umdat al-Salik”. Ruling M4.2(1) in its “Kafa’a” section states that non-Arab Muslim men can’t marry Arab Muslim women as Sunni hadith says that Arabs are superior to non-Arabs!

Ruling M4.2(3) then states that lower class men aren’t suitable in marriage for higher class women. Sunnism packs a punch with its combination of racial and class prejudice. Umar would be proud. Source: “Umdat al-Salik” (‘Reliance of the Traveller’), pp.523-524, Eng. trans
