It is narrated from Sayyida Aisha (may Allah be pleased with her) that a man sought permission to come to the Prophet Muhammad (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said about him: "He is a bad man of his family." Then, when he came to the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) treated him cheerfully and informally. After that man left, another man came. About him, the Prophet (peace and blessings be upon him) said: "He is the best man of his family." Then, when he came to the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) did not treat him as informally as he had treated the first one, nor was he as cheerful with him. When this man also left, I (Aisha) said: "O Messenger of Allah! When so-and-so sought permission from you, you declared him to be a bad man of his family, but then you treated him cheerfully and informally. And about so-and-so, you commented well, but did not treat him as you did the first one?" The Prophet (peace and blessings be upon him) said: "O Aisha! The worst people are those from whose evil others are cautious."
