It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) cursed those men who become effeminate, and those women who become masculine, and the Prophet (peace and blessings be upon him) said: "Expel such people from your houses." The Prophet (peace and blessings be upon him) himself expelled such a person, and Sayyiduna Umar (may Allah be pleased with him) also expelled such a person.
