Narrated Al-A`mash
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).' "
Narrated Abu Wail
We were in Siffin and Sahl bin Hunaif got up and said, "O people! Blame yourselves! We were with the Prophet (ﷺ) on the day of Hudaibiya, and if we had been called to fight, we would have fought. But `Umar bin Al Khatab came and said, 'O Allah's Messenger (ﷺ)! Aren't we in the right and our opponents in the wrongs' Allah's Messenger (ﷺ) said, 'Yes.' `Umar said, 'Aren't our killed persons in Paradise and their's in Hell?' He said, 'Yes.' `Umar said, 'Then why should we accept hard terms in matters concerning our religion? Shall we return before Allah judges between us and them?' Allah's Messenger (ﷺ) said, 'O Ibn Al- Khattab! I am the Messenger of Allah and Allah will never degrade me. Then `Umar went to Abu Bakr and told him the same as he had told the Prophet. On that Abu Bakr said (to `Umar). 'He is the Messenger of Allah and Allah will never degrade him.' Then Surat-al-Fath (i.e. Victory) was revealed and Allah's Messenger (ﷺ) recited it to the end in front of `Umar. On that `Umar asked, 'O Allah's Messenger (ﷺ)! Was it (i.e. the Hudaibiya Treaty) a victory?' Allah's Messenger (ﷺ) said, "Yes".

During the period of the peace treaty of Quraish with Allah's Messenger (ﷺ), my mother, accompanied by her father, came to visit me, and she was a pagan. I consulted Allah's Messenger (ﷺ), "O Allah's Messenger (ﷺ)! My mother has come to me and she desires to receive a reward from me, shall I keep good relation with her?" He said, "Yes, keep good relation with her."
