In the pre- Qur'anic, the word zawj is defined as a rug. In the Qur'anic period it is divided into two, namely Mecca and Medina. The Mecca period has a close meaning with the sign of the greatness of Allah and the pleasure that Allah gives. The Medina period contains the laws of separation. In the post-Qur'anic period, the word zawj describes gender equality, that men and women are the same components without being differentiated, so that there is a harmonious life in pairs.
