One of the most striking moral claims made by Muslims is that Islam did not merely teach private spirituality; it reformed a society. Among the examples often cited is the Quran's condemnation of female infanticide and its legislation of fixed inheritance shares for women.

This argument should be stated carefully. It does not prove that no one before Islam ever objected to the killing of girls, nor that every pre-Islamic Arab tribe practiced it universally. Rather, its force is that the Quran confronted a real and known practice among some Arabs, gave the murdered girl moral standing before God, and then embedded women's financial rights into sacred law through obligatory shares.

The argument at its strongest

The strongest version of the argument is this: Islam came to a society in which some families and tribes viewed daughters as a source of shame, economic burden, or tribal vulnerability. In such a setting, the Quran did not merely advise kindness. It condemned the shame attached to daughters, condemned the killing of children out of fear of poverty more generally, and placed the buried infant girl at the center of the scene of Judgement.

"And when the girl buried alive is asked: for what sin was she killed?" - Quran 81:8-9

This is a remarkable moral reversal. Classical tafsir treats the question as a devastating exposure of the killer's crime: the victim is asked, although she has no sin to confess, so that the injustice against her becomes undeniable. The verse does not need to name the father, the tribe, or the surrounding culture in order to condemn them; by centering the innocent victim on the Day when hidden crimes are made manifest, the Quran's wording makes the moral judgement unmistakable.

The Quran also describes the psychology behind such shame:

"And when one of them is given news of a female child, his face darkens and he suppresses grief. He hides himself from the people because of the evil of what he has been given: shall he keep her in humiliation or bury her in the dust? Unquestionably, evil is what they decide." - Quran 16:58-59

Here the Qur'an attacks not only the act but the value system behind it. It portrays the shame felt at the birth of a daughter as morally diseased. The father thinks the "bad news" is the girl; the Qur'an says the real evil is his judgement.

Then, in the same broad moral reform, the Quran gives women property rights in inheritance. It establishes a principle before giving details:

"For men is a share of what parents and close relatives leave, and for women is a share of what parents and close relatives leave, whether it is little or much - an obligatory share." - Quran 4:7

The key phrase is "an obligatory share." This was not a sentimental recommendation. It was a legal entitlement grounded in revelation. Women were not merely to be protected if male relatives felt generous; they were named as rightful heirs.

The Quran then gives specific shares, including for daughters. Many translations render the relevant clause as "two or more"; more precisely, the Arabic explicitly mentions more than two daughters, while the settled Sunni ruling is that two daughters also receive two-thirds:

"Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are only daughters, two or more, for them is two-thirds of one's estate. And if there is only one, for her is half..." - Quran 4:11

Whatever debates people have today about the distribution, the historical point is significant: daughters, wives, mothers, and sisters were given defined claims within a divine legal order. It should also be noted that "the male receives the share of two females" is not a universal rule for every inheritance case; shares vary by relationship and by which heirs are present, and in some cases women inherit the same as men in the same class, such as uterine siblings, or receive more than some male relatives because of the estate's configuration. This mattered especially in a tribal world where wealth, lineage, and protection were often organized through men, and where women could be vulnerable to being treated as dependents rather than legal persons.

Why this was a decisive reform

The Qur'anic reform operated at several levels.

  • It affirmed the moral worth of the female child. The buried girl is not a disposable burden. She is a human soul whose case is heard by God.
  • It condemned shame over daughters. Qur'an 16:58-59 does not treat the father's reaction as understandable pride; it calls his judgement evil.
  • It made women's inheritance a right. Qur'an 4:7 says women have a share "whether it is little or much," and calls that share obligatory.
  • It limited male control over wealth. A father or clan could no longer simply distribute everything according to tribal preference while excluding female heirs.
  • It tied reform to accountability before God. The issue was not only social policy; it was a matter of divine judgement.

This is important for the "Miracles of Islam" discussion because the Quran's moral authority did not remain an abstract ideal. It formed a community in which these rulings became part of religious law, worship, family life, and conscience. A practice known among some Arabs and associated with shame, vulnerability, or poverty was recast as a crime before God, while women who could otherwise be excluded were given enforceable claims.

The strongest counter-argument

A thoughtful critic may respond: "This is morally admirable, but it is not a miracle. Many societies have undergone moral reforms. Some pre-Islamic Arabs may already have disliked female infanticide. Jews, Christians, Romans, Persians, and others had various laws concerning women and inheritance before Islam. Also, the Qur'an does not establish full modern equality in inheritance, since in some cases a male receives the share of two females. So this proves only that Islam was a reforming movement, not that it was divine."

This is a serious objection and should not be dismissed. It is true that female infanticide was not practiced by every Arab family or every tribe. The evidence shows that the practice existed and was morally salient enough for the Quran to confront it, but it does not allow us to quantify its prevalence precisely. It is also true that some individuals before Islam may have condemned or prevented it. The argument should not be exaggerated into the claim that all pre-Islamic Arabs hated daughters or that no woman anywhere in the world had ever inherited property before the Quran.

It is also true that Islamic inheritance law is not identical to modern secular egalitarian assumptions. In some cases, such as sons and daughters inheriting together, the son receives twice the daughter's share. In other cases, the shares of male and female heirs can be equal, as with the father and mother when the deceased leaves children, or with uterine siblings. Muslims explain the system within the wider legal structure: in Islamic law, men carry mandatory financial duties such as maintenance of wives and children, while a woman's property remains her own. Still, a critic may say that this does not satisfy a modern expectation of identical shares.

So the argument, by itself, is not a mathematical proof that compels every sceptic. It is not like saying, "If Islam abolished this practice, therefore Islam must be divine." Moral reform alone can be interpreted in different ways.

The Muslim reply

The Muslim reply is more modest but still powerful. The claim is not that this single reform proves Islam in isolation. The claim is that it is one sign among many: the Qur'an's moral diagnosis, legal precision, spiritual authority, and actual transformation of society together point beyond ordinary human preference.

First, the Qur'an's language is not merely pragmatic. It does not say, "Do not bury girls because society needs more population," or "Do not do it because it weakens the tribe." It frames the matter in absolute moral terms: an innocent soul has been killed, and God will bring the crime to account. This gives the weakest human being - an unwanted infant girl - a dignity that no tribal calculation can erase.

Second, the Qur'an joins moral condemnation to legal construction. It is one thing to denounce cruelty; it is another to build a system in which women have specified financial rights. Qur'an 4:7 is especially important because it states the principle broadly: women have a share of inheritance, small or large, as an obligation. This is not charity. It is right.

Third, the reform was not merely theoretical. The early Muslim community received these verses as binding revelation. The rules of inheritance became part of Islamic law, studied and applied across Muslim societies. Muslims may have fallen short in practice at different times and places - as all communities fall short of their ideals - but the standard itself was clear and authoritative.

Fourth, the Qur'an's reform was balanced within its own worldview. Islam did not define justice as sameness in every financial allocation. It linked rights to responsibilities, inheritance to maintenance, and family law to accountability before God. A modern reader may still disagree with that framework, but it should be assessed on its own terms, not caricatured as a simple devaluing of women. The very verses sometimes criticized for unequal distribution are the verses that made female inheritance a divine entitlement.

What this does and does not establish

It does establish that the Qur'an confronted the killing of infant girls with uncompromising moral force. It also establishes that Islam granted women fixed inheritance rights in revelation, including daughters, mothers, wives, and other female relatives in relevant cases. In its Arabian context, this was a decisive moral and legal reform.

It does not establish that every pre-Islamic Arab practiced female infanticide, or that no other civilization had any concept of women's property rights. It also does not, on its own, prove Islam in a deductive sense to someone who rejects all religious premises. A fair presentation should avoid these overclaims.

What it strongly suggests is that the Qur'an speaks with a moral clarity and reforming power that is difficult to reduce to the prejudices of its environment. It elevated the most vulnerable, condemned a cruel cultural practice, and gave women enforceable rights within a sacred legal order. For a thoughtful reader examining the signs of Islam, that is not a trivial fact. It is part of the cumulative case that the Qur'an is not merely a product of its time, but a guidance that judged and transformed its time.

Conclusion

Islam's abolition of female infanticide and its legislation of women's inheritance rights are best understood as part of the Qur'an's wider moral revolution. The buried girl is given a voice before God, the shame over daughters is condemned, and women are named as rightful heirs. This argument should be presented honestly: it is not a stand-alone proof that removes every possible objection, but it is a powerful sign of the Qur'an's justice, authority, and transformative guidance.
