(How) that wherewith they were contented naught availeth them?

Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah
Chapter: Judging made on the basis of opinion or Qiyas
Narrated Al-A`mash:
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!"
