How many wives can a Muslim man have?

A Muslim man may marry up to four wives according to the classical reading of the Quran, but the same verse that names the number attaches a condition that changes everything: justice. If a man fears he cannot be fair, the Quran says, he marries one. A few pages later it adds that perfect fairness between wives is beyond any man, however hard he tries. Reading the two verses together, many scholars from Muhammad Abduh onward have concluded that one wife is the Quran’s norm and plural marriage a narrow exception.

What does the Quran say about how many wives a man can have?

The permission comes in Sūrat al-Nisāʾ, in a passage about orphans. After the Battle of Uhud left many children without fathers, some guardians wanted to marry the orphan girls in their care to get hold of their wealth without paying them a fair dowry. Aisha (may Allah be pleased with her) explained that the verse was revealed to stop this (Sahih al-Bukhari 4574):

فَٱنكِحُواْ مَا طَابَ لَكُم مِّنَ ٱلنِّسَآءِ مَثۡنَىٰ وَثُلَٰثَ وَرُبَٰعَ

“Then marry the women who are good for you: two, three, or four.”

Quran 4:3

The verse continues at once:

فَإِنۡ خِفۡتُمۡ أَلَّا تَعۡدِلُواْ فَوَٰحِدَةً

“But if you fear you will not be just, then one.”

Quran 4:3

The verse ends by saying this is “nearer to keeping you from injustice.” The number four sets a ceiling; justice decides whether a man may go past one at all.

What do the Sunni schools and the Shia say about four wives?

The Hanafi, Maliki, Shafi’i, and Hanbali schools and the Jaʿfari (Shia) school agree that four is the upper limit for a man’s wives at any one time. When Ghaylān ibn Salama of Thaqīf became Muslim with ten wives, the Prophet ﷺ told him to keep four (Jami’ al-Tirmidhi 1128, graded sahih by al-Albani). The Prophet’s own later marriages followed a ruling given to him alone (33:50).

His own life also shows what marriage meant to him. For twenty-five years he was married to Khadija (may Allah be pleased with her) and to no one else, and he spoke of her with love long after her death. Most of the women he married after her had been widowed or divorced, several of them by war.

Can a husband be fair to more than one wife?

The Quran answers this question itself, in the same surah:

وَلَن تَسۡتَطِيعُوٓاْ أَن تَعۡدِلُواْ بَيۡنَ ٱلنِّسَآءِ وَلَوۡ حَرَصۡتُمۡ

“You will never be able to be fully just between wives, however much you wish to.”

Quran 4:129

The classical jurists read 4:129 as speaking of the heart’s inclinations, which a man cannot control, while 4:3 asks for fairness in nights, money, and care, which he can. The verse still commands a husband “not to lean entirely to one and leave the other hanging.” Fairness in time and money was the minimum; the Quran’s honesty about the heart was a warning.

What did Muhammad Abduh and the reformers say?

Muhammad Abduh (d. 1905), Grand Mufti of Egypt, read these verses together with the harm he saw in the families of his day: wives neglected, children of different mothers set against one another. Taught by the principle that preventing harm comes before securing benefit, he held that plural marriage is permissible only in cases of real necessity, and that a ruler may restrict it when it causes harm. His student Rashid Rida carried the argument into their commentary, Tafsīr al-Manār.

In Tunisia, the scholar Tahar Haddad argued in 1930 for ending polygyny altogether, and Tunisia’s Code of Personal Status of 1956 prohibited it. Other Muslim-majority countries chose to regulate. Morocco’s family code of 2004 requires a judge’s permission, a serious justification, and proof that the husband can support both families equally; the first wife must be informed and may oppose it, and a monogamy clause in her contract rules out a second marriage. Algeria and other states have similar rules.

Does a man need his first wife’s permission?

The classical schools did not require it. The tradition still gave women a way to protect themselves. In the Hanbali school, a bride may make it a condition of her contract that her husband takes no other wife, and if he breaks it she may end the marriage. The Prophet ﷺ said that the conditions most deserving to be honored are those of the marriage contract (Sahih al-Bukhari 2721).

The Prophet ﷺ himself refused to let his son-in-law ʿAli take a second wife while married to his daughter Fatima. Standing on the pulpit, he said:

«فَإِنَّمَا هِيَ بَضْعَةٌ مِنِّي، يُرِيبُنِي مَا أَرَابَهَا وَيُؤْذِينِي مَا آذَاهَا»

“She is a part of me. What troubles her troubles me, and what hurts her hurts me.”

Sahih al-Bukhari 5230

Every wife is someone’s daughter. The stronger view (al-rājiḥ) today, given the Quran’s demand for justice and the Sunnah’s care for Fatima, is that a plural marriage is lawful only with the free and informed consent of every spouse. Consent is the foundation of any marriage (Is forced marriage allowed in Islam?), and a wife who did not agree to share her marriage has been wronged. She may seek a divorce if she wishes (Is divorce haram in Islam?).

Is it haram to marry a second wife in secret?

A secret second marriage fails every test the Quran sets. It deceives the first wife, it usually leaves the second wife without legal protection, and in most Western countries it breaks the law that Muslims have promised to keep. “Fulfill your contracts,” the Quran commands (Quran 5:1). Justice that has to be hidden is no justice at all.

How should Muslims understand plural marriage today?

Plural marriage met a need in a society of war widows and orphans, and the Quran surrounded it with conditions that point toward one spouse. Muslims who choose monogamy follow the conclusion the Quran itself draws. Where everyone involved freely consents, is truthful, and is treated with equal dignity, the wider questions of plural relationships are taken up in Is polyamory haram in Islam?, and the Quran’s vision of women’s equal standing in What does the Quran say about women?.

The Quran describes spouses as garments for each other (Quran 2:187): close, protecting, and covering each other’s faults. Whatever shape a marriage takes, its measure before Allah is the same: whether each person in it is treated with justice, honesty, and tenderness. May Allah fill every Muslim home with that mercy.
