If a Muslim man marries another woman, isn't that unfair to his first wife? Let's understand what Islam really says about this, and why this permission was given in the first place.
In Islam, a man is allowed to marry up to four wives, but that doesn't mean he should. It's a permission, not a command.
And this permission came at a very specific time and for a very specific reason. After the Battle of Uhud, many Muslim men were martyred, leaving behind widows and orphans with no one to care for them.
Back then, there were no governments or systems to support these families.
Women and children depended completely on the men of their families for shelter, protection, and survival.
To prevent widows and orphans from being neglected,
Allah revealed verse 3 in Surah An-Nisa. If you fear that you will not deal justly with the orphans, then marry those that please you of women, two, three, or four.
But if you fear that you will not be just, then marry only one.
This verse was not revealed to give men freedom for their desires.
It was revealed to bring justice and care into a society that was struggling after the war. It was meant to protect, not to exploit. Allah made justice the main condition. A man can marry another woman only if he knows he can treat all his wives equally, in time, in money, in care, and in attention.
If he cannot be fair, then the Quran clearly says, marry only one. Islam does not say a man must have a reason, like his wife being sick or unable to have children. He can marry again without those reasons. But if he does it out of selfishness, boredom, or simply because he lost feelings for his first wife, then he's already being unfair.
Because when the heart leans toward one wife more than the other, justice becomes impossible.
And that is exactly what Islam forbids.
The Prophet said, whoever has two wives and favors one over the other will come on the day of judgment with one side leaning.
This shows how serious this matter is.
Islam allows polygamy not to hurt women but to protect them.
