صلح الحسن مع معاوية

The peace between al-Hasan ibn Ali and Mu'awiya took place at Maskin in 41 AH, and then al-Hasan went back to Medina. ¹

Al-Suyuti relates that al-Hasan took the caliphate after his father's killing by the allegiance of the people of Kufa; he stayed for six months and some days, then Mu'awiya marched against him. Al-Hasan offered to hand over the matter on conditions Al-Suyuti names: that the caliphate should be his after him, that no one from Medina, the Hijaz or Iraq be called to account for anything of his father's days, and that his debts be paid. Mu'awiya agreed to this. Al-Suyuti says the renunciation was in Rabi al-Awwal 41 AH according to the well-known account. ²

He quotes al-Hasan saying to someone who blamed him that he had not wished to fight them for the kingdom, and that he left the matter seeking the face of God and to spare the blood of the community. ²

Al-Mas'udi says that Amr ibn al-As (may God be pleased with him) advised Mu'awiya, in Kufa, to order al-Hasan to preach. Al-Hasan stood and preached, mentioned what had befallen Kufa in the plunder of his pavilion and the stabbing in his side, and then submitted to the peace. ³

Mu'awiya sent Busr ibn Abi Artat to Basra in Rajab 41 AH. ⁴
