Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that during the time of the Messenger of Allah (peace and blessings of Allah be upon him), two men abused each other. One of them used foul language while the other remained silent, and the Prophet (peace and blessings of Allah be upon him) was also present. Then the second person also responded, so the Prophet (peace and blessings of Allah be upon him) stood up and left. It was said to him: "You have stood up?" The Prophet (peace and blessings of Allah be upon him) said: "When the angels departed, I also left with them. As long as he remained silent, the angels were responding to the one who was abusing, but when he replied, the angels departed."

It is narrated from Sayyida Umm Darda’ (may Allah be pleased with her) that a man came to her and said: A man has spoken ill of you in the presence of Abdul Malik. She replied: If someone says something about us which is not in us, then sometimes it also happens that people praise us undeservedly.

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him), he says: When a man says to his companion, "You are my enemy," then one of them goes out of Islam, or he becomes disassociated from his companion. Qais (may Allah have mercy on him) says that later Abu Juhaifah informed me that Abdullah (may Allah be pleased with him) said: Yes, if he repents (then it is another matter).
