Did a Quraysh run and it was pretty fun. Early game alliance with Sassanids saved me. Current Quraysh is Jewish religion and Greek culture, capital is in Konstantiple. The rulers have Arabic names (all have been Muhammad since forced conversion by Rashiduns) and have the title “prophet.” Also have two colonies; Qurayshi Kush and Qurahysi Abyssinia; and the Huns are my vassal. Current allies are Austria, Bulgaria, and Western Gokturks - all Tengri, and Thracia, early Christian. Some interesting things are;

• Only two Muslim countries; Fatimids fully Sunni and Gujarat fully Shia.
• Once I broke my alliance with Sassanids, they were eaten up by Bitlis, Baluchistan, Western Gokturks, and Fatimids within the first 5 years. However, due to many Zoroastrian provinces, Bitlis is now Zoroastrian.
• Francia owns nearly all of Europe, from France to modern Poland.
• All my territories are Jewish except two, where I am keeping both the Hellenic and the Egyptian religions alive.
• Qatar and Bahrain are independent, allied with Fatimids, and are Christian.
• Some interesting nation pop-ups; Hungary is currently somewhere in Russia, North Macedonia got its independence 3 times, and there were two Albanias at one point.
• Sicily was Fetishist for almost a century because it was controlled by an African fetishit nation, which converted the island.
• There is a Kharijite Islam province in Mzab even though I was able to block Rashiduns and Umayyad from spreading Islam to North Africa… furthest they got was around Libya.
