Marriage Of Pre-Islamic Arabian Society

I read The Sealed Nectar by Safiur-Rahman Al-Mubarakpuri and came across Arab society before Islam. Basically, there's 4 types of marriage before islam came to Arab society. The first is the present day marriage which a man give his daughter after a proposal from a man with a dowry that has been agreed. Second, is a man would send his wife to cohabit with another man. Later on, if the woman got pregnant he would choose whether or not to be with her. Third is a group with less than 10 men would have sexual intercourse with a woman. Once she conceived and gave birth, she would send for these man and pointed out to the father of her child. Lastly,any number of man can sleep with a woman. She would put a flag at the gate of their house to invite in anyone who like. If she conceived and got pregnant, she would collect these man and a seeress would tell which is the father of the child. When Islam came, all kind of marriage were prohibited except for the first one.

I decided to explore the third kind of marriage for Fiqh subject so I Google polyandry. Polyandry is a a woman married with more than one man at the same time. It's totally prohibited in Islam unlike polygyny which a man can have one, two, three or four wives at one time. Logically, it's not relevant enough for a woman to point which guy she was with to be the father of her child. If that is the case then what about doing DNA test to verify who the father is? DNA test is not as easy as it looks. The test would take weeks or years to obtain the result officially. If it's that easy then I wondered why some of the crime cases had not been solved yet? Then, a conflict would arise regarding the child's name. Which dad's name should the baby have? After all, the DNA test is not complete yet. Another problem is the time spent for a wife to be with each husband. Naturally, a woman would have her menstruation cycle. If it is one of her husband's nights to be with her when she's period, obviously it would not be fair for him unlike other husbands.

In short, there are tonnes of issues regarding polyandry. It would be difficult for a woman to handle a lot of husbands at one time. Thus, Allah had prepared us the best medicine which is polygyny that are very suitable with human nature. Of course, there are still a lot of aspect that need careful attention for a man to have more than one wife.
