One more point, although covered indirectly, need direct reference. This comes from the last part of the Khutbah relating to the equality of all human beings, Muslims and non-Muslims:
People, your Rabb (Creator and Sustainer) is One, and your father is one. Verily an Arab has no preference over a non Arab nor a non Arab over an Arab nor a White over a Black nor a Black over a White except for being more Allah-Conscious (illā bi al-Taqwā).23
This establishes the principle, not only of one brotherhood of Muslims, but also one brotherhood of humanity.
