The Prophet—may Allah bless him and grant him peace—said, “He is not one of us who calls to tribal partisanship; he is not one of us who fights for tribal partisanship; and he is not one of us who becomes angry because of tribal partisanship.” (1)
He also said, may Allah bless him and grant him peace, “Allah has removed from you the arrogance of the Age of Ignorance and its boast of lineage. You are either a pious believer or a wretched sinner. All people are the children of Adam, and Adam was created from dust; an Arab enjoys no superiority over a non-Arab except through God-fearingness.” (2)
These factional loyalties divide the Muslims, whereas Allah has commanded us to unite and to cooperate in righteousness and piety, and He has forbidden division and discord. The Exalted says: “And hold fast, all together, to the rope of Allah and do not be divided. Remember Allah’s favor upon you: when you were enemies He brought your hearts together, and by His grace you became brothers.” (Qur’an 3:103)
Allah, glorified be He, wants us to be a single party—namely, the Party of Allah, the ones who will prosper
