Sororal polygyny
Sororal polygyny is a type of marriage in which two or more sisters share a husband.

There is a prohibition of sororal polygyny in Leviticus 18 – at least its consummation, during the lifetime of the original wife:

"1 The LORD said to Moses, 2 "Speak to the Israelites and say to them: 'I am the LORD your God. ... 4 You must obey my laws and be careful to follow my decrees. I am the LORD your God...."

6 No one is to approach any close relative to have sexual relations. I am the LORD.

[...]

18 Do not take your wife’s sister as a rival wife and have sexual relations with her while your wife is living."

In Islam, this type of polgyny is similarly specifically prohibited. Reference from Quran (Chapter 4, verse 23): "Forbidden unto you are your mothers, and your daughters, and your sisters, and your father's sisters, and your mother's sisters, and your brother's daughters and your sister's daughters, and your foster-mothers, and your foster-sisters, and your mothers-in-law, and your step-daughters who are under your protection (born) of your women unto whom ye have gone in - but if ye have not gone in unto them, then it is no sin for you (to marry their daughters) - and the wives of your sons who (spring) from your own loins. And (it is forbidden unto you) that ye should have two sisters together, except what hath already happened (of that nature) in the past (before this revelation). Lo! Allah is ever Forgiving, Merciful."
