Islam, specifically Sunni Islam.
Most African Arabs were Muslims and while most African Arabs today are Sunnis, historically, there was a mix of Sunni and Shiite Muslims. A minority of African Arabs are Christians.
Kurds, Arabs, and Persians are ethnic groups that are primarily focused in the Middle East. Kurds are overwhelmingly Sunni Muslims, but there are minorities of Shiite Kurds (especially in Iran), Alevi Kurds, Yezidi Kurds, Yarsan Kurds, and other religious minorities. There are some Jewish Kurds who predominantly live in Israel. Arabs are predominantly Sunni Muslims, but there are large minorities of Shiite Muslim Arabs, especially in Iraq, Bahrain, Saudi Arabia, and Kuwait. There are also Ibadi Muslim Arabs, Alawite Arabs, numerous Christian Arabs, Druze Arabs, Baha'i Arabs, and other minority religions. Persians are overwhelmingly Shiite Muslims, but there are minorities of Sunni Persians, Jewish Persians, and several other minority religions.
It depends on whether you consider "Arab" to be a united ethnic group or if it is divisible along ethno-religious lines. If Sunni Arabs and Shiite Arabs are distinct ethnic groups, then Sunni Arabs form Iraq's second largest ethnic group (after Shiite Arabs). If the Arabs are a united ethnic group, then the Kurds form the next largest ethnic group.
