It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The strong man is not the one who quickly throws (someone) down; rather, the strong man is the one who controls himself at the time of anger."

Muhammad bin Abdullah bin Amr bin Uthman (may Allah have mercy on him) reports that the Prophet (peace and blessings be upon him) said: "The worst usury (riba) is reviling people's honour, and the most severe reviling is satire (hija'), and the one who transmits it is one of the two revilers."
This is mursal, and it supports the previous narration. Imran bin Anas al-Makki narrated it from Ibn Abi Mulaykah, from Sayyidah Aishah (may Allah be pleased with her), from the Prophet (peace and blessings be upon him) with a connected chain in the first wording; Imam al-Bukhari (may Allah have mercy on him) said: He was not corroborated in it.

Sayyidah Aishah (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings be upon him) said: "The greatest liar among people is a man who satirizes a man and thereby satirizes his entire tribe, and a man who disowns his father and accuses his mother of fornication."
