It is narrated from Sayyiduna Umar (may Allah be pleased with him) that he said: "There are four types of people upon whom Allah is angry in the evening and in the morning He is wrathful with them: men who imitate women, women who imitate men, those who commit bestiality, and those who commit the act of the people of Lut." And Sayyiduna Umar (may Allah be pleased with him) said: "There are four things that are permissible and obligatory for everyone: emancipation, divorce, vow, and marriage."
