The wisdom of polygyny and criticism of it

1The legal position: conditionally permissible

The basic ruling on polygyny is that it is permissible (mubah) on condition of justice and means (Surah an-Nisa' 4:3). Scholars then explained that the ruling can change according to the individual's circumstances:

• It is recommended to be content with one wife if there is no clear need — this is the view stated in the authoritative books of the Shafi'i school (for example Mughni al-Muhtaj, al-Khatib ash-Shirbini) and the Hanbali school (for example Kashshaf al-Qina'), on the evidence of the end of verse 4:3: "that is nearer to preventing injustice".
• Some other scholars see polygyny as a sunnah, or preferable for those who are able and confident they can be just, based on the practice of the Companions.
• Forbidden for a person who is certain, or strongly suspects, that he will be unjust.
• Reformist scholars such as Muhammad Abduh (in Tafsir al-Manar) took a very strict view, seeing polygyny as a permission for emergencies only because of the widespread injustice of his time. Many other scholars criticised this view for narrowing what Allah has made permissible.

2The wisdom mentioned by scholars

The following wisdom is the interpretation and ijtihad of scholars, not texts that state the reason for the ruling exhaustively. The permissibility of polygyny does not depend on any one of these wisdoms being present.

3Criticisms and concerns

The following concerns are raised by researchers, activists, counsellors and scholars too. Some are aimed at wrong practice, not the ruling itself — but all deserve to be taken seriously:

• Injustice in practice — unjust rotation and maintenance, the first wife neglected, or the new wife kept secret.
• Emotional and health effects on the wife — stress, a sense of betrayal and loss of trust, especially when polygyny happens without discussion.
• Effects on children — rivalry between families, less time with their father, and inheritance conflicts.
• Secret polygyny — marrying abroad or without court permission makes it hard for the wife and children to claim their rights, and the existing wife is given no chance to voice an objection.
• Financial means — the burden of two households often lowers the existing family's standard of living.
• Power imbalance — a woman who is financially dependent may not be truly free to agree or refuse.

The views of contemporary scholars also vary: some stress strengthening court procedures and pre-marriage education, some support conditions or taʿliq that give the wife the right to choose, and some insist that the main problem is practice that does not conform to the Shariah, not the ruling itself. All these views agree that injustice towards wives and children is forbidden.

4What the courts show

In Malaysia, polygyny applications are assessed by the Syariah Court. Some applications are refused because the applicant fails to prove financial means, need or the ability to be just, or because of harm to the existing wife. The Syariah Judiciary Department Malaysia (JKSM) and the state courts publish case data; the figures vary by state and year.

5The Shariah's answer: the condition of justice and court control

The Shariah does not answer these concerns by denying them, but by imposing restrictions:

• The condition of justice (Surah an-Nisa' 4:3, 4:129) — a fear of injustice is enough to prohibit polygyny for that individual.
• The prohibition of harm — the maxim "la darar wa la dirar" (no harm and no reciprocating harm; narrated by Ibn Majah, graded hasan by an-Nawawi).
• Conditions in the marriage contract and taʿliq — a wife may stipulate conditions or obtain protection through taʿliq (conditional divorce) (see conditions & taʿliq).
• Court control — in Malaysia, Act 303 s.23 and the state enactments require the permission of the Syariah Court, which weighs the need, financial means, ability to be just and harm to the existing wife. Marrying without permission is an offence (Act 303 s.123).
• The existing wife's rights — she may attend and be heard in the application, and may apply for judicial dissolution (fasakh) or a maintenance order if she is wronged.

6What are NOT valid reasons

No text sets an official list of reasons, but based on the condition of justice, the prohibition of harm and court practice, the following are not proper grounds:

• Mere desire without the means and readiness to bear responsibility — marriage is built on trust, not a passing wish.
• Revenge or punishing the wife — using a new marriage to hurt the existing wife goes against the prohibition of harm (Surah al-Baqarah 2:231: "do not keep them to harm them").
• Showing off or status — the number of wives is not a measure of success or piety.
• Running away from problems at home without trying to fix them — those problems usually move into the second household.
• Financial interest in the prospective wife's property.

7Weighing it honestly

• For a husband: ask whether you can give full maintenance, equal time and just attention to every wife and child — today and ten years from now.
• For an existing wife: you have the right to know, to voice your views in court, and to claim your rights. Consent is not required for the validity of the marriage contract in classical fiqh, but the courts in Malaysia take your views into account.
• For a prospective wife: make sure the application is made through the court and the marriage is registered so that your rights and your children's are secured.
• Get counselling before making a decision.

8A note on honesty: the orphan context in an-Nisa' 4:3

The polygyny verse (Surah an-Nisa' 4:3) was revealed in the context of orphans. Aishah r.a. explained that it concerned an orphan girl under the care of a guardian who wished to marry her without giving her a fair mahr — so the guardian was told to marry other women (Sahih al-Bukhari 4574; Sahih Muslim, Kitab at-Tafsir).

It is about justice to the weak, not men's desire. Many scholars also mention protecting widows as a wisdom — but that is interpretation, not the occasion of the verse's revelation. Any list of "benefits" that forgets this context has turned the verse upside down.
