It is narrated from Sayyidah Aisha (may Allah be pleased with her) that a man sought permission to visit the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "This person is a bad man of his tribe." When he came in, the Prophet (peace and blessings be upon him) received him with a cheerful face. So I asked the Prophet (peace and blessings be upon him) about this, and he said: "Allah does not like the one who is foul-mouthed and ill-spoken."
