That he heard the Prophet (ﷺ) delivering a sermon, and he mentioned the shecamel and the one who hamstrung it. Allah's Messenger (ﷺ) recited:-- 'When, the most wicked man among them went forth (to hamstrung the she-camel).' (91:12.) Then he said, "A tough man whose equal was rare and who enjoyed the protection of his people, like Abi Zama went forth to (hamstrung) it." The Prophet (ﷺ) then mentioned about the women (in his sermon). "It is not wise for anyone of you to lash his wife like a slave, for he might sleep with her the same evening." Then he advised them not to laugh when somebody breaks wind and said, "Why should anybody laugh at what he himself does?"
