Abstract: In Islamic law, it is preferable for a man to have only one wife, even if he can keep her to the end. Islam teaches that marriage must create an atmosphere of sakinah, mawaddah and mercy. The atmosphere is difficult to do if a man has more than one wife. Justice as a condition of creating harmony between wives is very difficult to happen. Therefore religion warns Norma to practice polygamy and choose one wife at the same time. The results of this study reveal that there are still many men who have an understanding and carry out this polygamous marriage without paying attention to the terms and conditions contained in Islamic law.
