question #2 Sahih al-Bukhari 7308, Book 96, Hadith 39 : How can historical battles like Siffin influence our understanding of conflict resolution in Islam?

I asked Abu Wail, “Did you witness the battle of Siffin between `Ali and Muawiya?” He said, “Yes,”
and added, “Then I heard Sahl bin Hunaif saying, ‘O people! Blame your personal opinions in your
religion. No doubt, I remember myself on the day of Abi Jandal; if I had the power to refuse the order
of Allah’s Messenger (ﷺ), I would have refused it.
We have never put our swords on our shoulders to get involved in a situation that might have been
horrible for us, but those swords brought us to victory and peace, except this present situation.’ ” Abu
Wail said, “I witnessed the battle of Siffin, and how nasty Siffin was!”
