When Al-Hasan bin ʿAli moved with army units against Muawiya, ʿAmr bin AL-As said to Muawiya, "I see an army that will not retreat unless and until the opposing army retreats." Muawiya said, "(If the Muslims are killed) who will look after their children?" ʿAmr bin Al-As said: I (will look after them). On that, ʿAbdullah bin 'Amir and ʿAbdur-Rahman bin Samura said, "Let us meet Muawaiya and suggest peace." Al-Hasan Al-Basri added: No doubt, I heard that Abu Bakra said, "Once while the Prophet was addressing (the people), Al-Hasan (bin ʿAli) came and the Prophet ﷺ said, 'This son of mine is a chief, and Allah may make peace between two groups of Muslims through him."
