It is narrated from Umm al-Mu'minin Sayyida Aisha (may Allah be pleased with her) that a man sought permission to come to the Messenger of Allah (peace and blessings be upon him) while I was with him in the house. The Messenger of Allah (peace and blessings be upon him) said: "He is a bad man." Then the Messenger of Allah (peace and blessings be upon him) gave him permission to enter. Sayyida Aisha (may Allah be pleased with her) says that not much time had passed when I heard the Messenger of Allah (peace and blessings be upon him) laughing with him. When he left, I said: O Messenger of Allah (peace and blessings be upon him)! Just now you called him bad, and now you are laughing with him. The Messenger of Allah (peace and blessings be upon him) said: "The worst among people is the one whom people avoid or fear because of his evil."
