But also to have more children. This is common in tribal societies where the more people the stronger the tribe and family. There is nothing wrong with polygamy if the culture supports that. Marriage means different things to different societies and cultural norms. The Koran did not come to change society. Thats Sunni talk. It came to change people's religion and ethics hence the emphasis on treatment on the Koran regarding wives.
Polygamy actually benefits the wealthy who can easily support more than one wife. In fact a caliph or king can support 100s of wives and when there is no even wealth distribution becoming part of a harem is almost the only choice for a woman. Polygamy does not benefit poor honest hard working men, let alone does it reflect the purpose of marriage from God nor does it reflect in any measure the notion of love.
We know many prophets, including Muhammad had more than one wife. But the question here is equal treatment at least to the best of one's ability. If some societies do not approve of that then they don't have to allow it. There is nothing called you can not marry more than four wives. Thats Sunni talk. The verse never said that. Tow, three and four is just an expression of polygamy but not a limitation. The Koran uses such expression.
One thing I don't think Muslims understand is that those prophets while favored by God did do many bad things that God was displeased with. The relationship between God and the OT biblical figures is more complex than Muslims are led to believe. It is not a simple matter of 'oh he is a prophet therefore he is sinless'. Many of those prophets did many evil things.
The reality is these practices were always there and were there in many societies in Africa, Middle East or even Asia. The Koran came to change people's religion and not culture or practice unless its oppressive such as burying alive of daughters etc. If societies have problems with polygamy there is no reason why they can't abolish it if they chose or they can allow it if they chose. Can women marry more than one husband? have not seen any reason form the Koran why this can't be allowed also. If this is the cultural norm so be it.
I think it is a socially destructive practice that only has merit in extreme circumstances. Yes there may be times and places where populations are imbalanced. Overall it is sexist, breeds jealousy both from outside and within and never fosters love and certain is not what God intended for marriage.
In haj we know that many of these rituals were practiced by pagans and many other societies have religious rituals and rites. The Koran never came to change that but change to whom we should worship and not how. Thatw why Sunni always ask how do we do this and how then do we do that. These things probably existed before Koran and the Koran wen't along with it. The same case with food restriction for the Israelites. The Koran said that these restrictions were there before Moses was even before so God might have wen't along with that. In other times it can be a trial as the case with the Sabbath. The Koran says the Sabbath was introduced as a trial for the Israelites as the case of the direction of Qibla was a trial. It then made it clear that it was there for a specific purpose and it does not reflect a religious tradition as verse 2:177 tells us.
You pretty much have to ignore the New Testament and Jesus teachings on rituals and food. Even if you stop short of saying Jesus is God, there is so much that Jesus taught that Mohammad simply overrides again. Considering you disagree with the Sunni then I have to question on what basis because you are also arguing that Mohammad was right and Jesus was wrong. Either ritual is important or it is not.
Sure believe in God and one God and sure question the hadith but don't impose polygamy on the world again. Let's learn about love and one way to learn about love given to us by God is marriage and his intention, which is commitment to one person.
I concede there can be practical reasons for polygamy however these are extreme situations that do not apply to our lives today and rarely if ever applied in history.
It's simple to disprove polygamy - would you want your partner to be cheating on you?
