Volume 9, Book 88, Number 225:
Narrated Al-Hasan Al-Basri:
When Al-Hasan bin ‘Ali moved with army units against Muawiya, ‘Amr bin AL-As said to Muaw –
iya, “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?” ‘Amr bin Al-As said: I (will look after
them). On that, ‘Abdullah bin ‘Amir and ‘Abdur-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 ‘Ali) came and the Prophet said, ‘This son of mine
is a chief, and Allah may make peace between two groups of Muslims through him.”
