Hello! I'm writing a school project about how the islamic caliphate went from, after the death of Muhammad, civil war and fitna to developing into the islamic golden ages. Could anyone that has much knowledge in the subject tell me about what led to the first fitna and the consequences that led to the islamic golden ages?
Jazak'allah
