Volume 4, Book 53, Number 405:
Narrated Al-Amash:
I asked Abu Wail, “Did you take part in the battle of Siffin?” He said, ‘Yes, and I heard Sahl bin
Hunaif (when he was blamed for lack of zeal for fighting) saying, “You’d better blame your wrong
opinions. I wish you had seen me on the day of Abu Jandal. If I had the courage to disobey the
Prophet’s orders, I would have done so. We had kept out swords on our necks and shoulders, for a
thing which frightened us. And we did so, we found it easier for us, except in the case of the above
battle (of ours).’ “
