In Saudi Arabia, polygamy is permitted by Islam and is legal under certain conditions. According to Islamic law, a man is allowed to marry up to four wives as long as he can support them financially and treat them all equally. However, there are strict regulations in place to prevent abuse of this practice and to protect the rights of women.

For a man to marry a second, third, or fourth wife, he must obtain permission from a Sharia court and provide valid reasons for why he wishes to take on additional wives. The court will then consider whether the man is capable of supporting multiple wives and treating them all fairly before granting permission.

It is important to note that while polygamy is legal in Saudi Arabia, it is not as common as it once was. Many Saudis now choose to only have one spouse due to changing social norms and economic factors. Additionally, some women in Saudi Arabia are pushing for more rights and equality within marriage, making polygamy less appealing to some men.

Overall, while a man can legally marry two wives in Saudi Arabia, it is not a widespread practice and is heavily regulated to protect the rights of women. Each case is carefully considered by the Sharia court to ensure that the practice is not being abused and that all parties involved are treated fairly.
