The Battle of Siffin can be seen as the natural outcome of the Battle of Jamal. The Battle of Jamal paved the way for those who were enemies of Islam to now have an excuse to fight the caliph of the Muslims, even if they were absolutely inferior to Imam Ali (as) when it came to companionship of the prophet (s). The worst part of this battle was the imposed arbitration that led to the added strength to Muawiyah and his rule.
