The Koran says a man can marry more than one wife. No indication, though, is given whether a woman can marry more than one husband.

And if you fear that you cannot act equitably towards orphans, then marry such women as seem good to you, two and three and four; but if you fear that you will not do justice (between them), then (marry) only one or what your right hands possess; this is more proper, that you may not deviate from the right course. Surah 4:3

The Koran says a man cannot marry more than four. The Koran says you can exchange one wife for another, as long as you don’t take her inheritance.

And if you wish to have (one) wife in place of another and you have given one of them a heap of gold, then take not from it anything; would you take it by slandering (her) and (doing her) manifest wrong? Surah 4:20

Yet the Koran says a man can commit adultery against his wife, unless he marries the other woman before he has sex with her.

And all married women except those whom your right hands possess (this is) Allah’s ordinance to you, and lawful for you are (all women) besides those, provided that you seek (them) with your property, taking (them) in marriage not committing fornication. Then as to those whom you profit by, give them their dowries as appointed; and there is no blame on you about what you mutually agree after what is appointed; surely Allah is Knowing, Wise. Surah 4:24

While many of the Bible characters had multiple wives, it was never God’s plan for that to happen. God always made a covenant and promise with someone and their first wife (Abraham-Sarah). Other wives, and their offspring, always caused disagreement and trouble. The Bible says pastors of churches must only have one wife.

Now the overseer must be above reproach, the husband of but one wife, temperate, self-controlled, respectable, hospitable, able to teach, not given to drunkenness, not violent but gentle, not quarrelsome, not a lover of money. 1 Timothy 3:2

One wife has always been the standard for marriage since God made Eve for Adam. Marriage was never a necessity, but a choice. Jesus did not marry. Nor did the Apostle Paul.
