By Allah, Al-Hasan bin `Ali led large battalions like mountains against Muawiya. `Amr bin Al-Assaid (to Muawiya), "I surely see battalions which will not turn back before killing their opponents."Muawiya who was really the best of the two men said to him, "O `Amr! If these killed those and thosekilled these, who would be left with me for the jobs of the public, who would be left with me for theirwomen, who would be left with me for their children?" Then Muawiya sent two Quraishi men fromthe tribe of `Abd-i-Shams called `Abdur Rahman bin Sumura and `Abdullah bin 'Amir bin Kuraiz toAl-Hasan saying to them, "Go to this man (i.e. Al-Hasan) and negotiate peace with him and talk andappeal to him." So, they went to Al-Hasan and talked and appealed to him to accept peace. Al-Hasansaid, "We, the offspring of `Abdul Muttalib, have got wealth and people have indulged in killing andcorruption (and money only will appease them)." They said to Al-Hasan, "Muawiya offers you so andso, and appeals to you and entreats you to accept peace." Al-Hasan said to them, "But who will beresponsible for what you have said?" They said, "We will be responsible for it." So, whatever Al-Hasan asked they said, "We will be responsible for it for you." So, Al-Hasan concluded a peace treatywith Muawiya. Al-Hasan (Al-Basri) said: I heard Abu Bakr saying, "I saw Allah's Messenger (ﷺ) on thepulpit and Al-Hasan bin `Ali was by his side. The Prophet (ﷺ) was looking once at the people and once atAl-Hasan bin `Ali saying, 'This son of mine is a Saiyid (i.e. a noble) and may Allah make peacebetween two big groups of Muslims through him."
