What Does the Torah Say About Masturbation — and How Do Judaism, Christianity & Islam Compare?

The Torah itself contains no verse that explicitly forbids masturbation. Rabbinic authorities have historically derived a prohibition — particularly for men — from the concept of hash-chatat zera, the 'destruction' or 'wasting' of seed. The classic prooftext is the story of Onan in Genesis 38, though that narrative concerns a specific covenantal obligation rather than solitary acts. The Torah's sexual legislation in Leviticus 18 focuses on prohibited relationships and the uncovering of nakedness Leviticus 18:7, not on solitary behavior, leaving interpreters to extrapolate Leviticus 18:17.

Medieval authorities like Maimonides (12th century) treated the prohibition as serious, while later Ashkenazic codes such as the Shulchan Aruch (Joseph Karo, 1563) reinforced it. The concern is framed less around a specific Torah verse and more around broader principles of sexual holiness. Deuteronomy's prohibitions on sexual immorality and the categories of toevah (abomination) Deuteronomy 18:12 are sometimes invoked as a general framework, though they do not name masturbation directly Deuteronomy 12:31.

Modern Orthodox, Conservative, and Reform authorities diverge considerably. Rabbi David Feldman's 1968 work Birth Control in Jewish Law surveyed the range of opinion and found the prohibition less absolute than often assumed, especially for women, for whom the 'wasting seed' rationale does not apply. It's fair to say there's genuine disagreement within Judaism today, and the Torah text itself doesn't settle the question.

Christianity doesn't have a single authoritative ruling on masturbation, and the New Testament is as silent on the specific act as the Torah is Exodus 20:14. Early Church Fathers, drawing on the same Onan narrative and on Stoic ideas about the purpose of sexuality, condemned it strongly. Augustine (4th–5th century) and later Thomas Aquinas (13th century) classified it as contrary to natural law because it separates sexual pleasure from procreation.

The Roman Catholic Church maintains a formal prohibition, articulated in the Catechism of the Catholic Church (1994, §2352), grounding it partly in the broader biblical call to avoid sexual immorality — a category that Deuteronomy's legislation helps define Deuteronomy 5:18. Protestant traditions are far more varied. Many Reformed and evangelical theologians acknowledge the absence of an explicit biblical text and counsel pastoral sensitivity rather than blanket condemnation.

The Torah's adultery prohibitions Exodus 20:14 and its broader framework of sexual holiness Deuteronomy 23:17 are seen by Christian interpreters as background context for New Testament ethics, but they don't resolve the masturbation question on their own. Scholars like William Webb (Slaves, Women & Homosexuals, 2001) argue for a 'redemptive-movement hermeneutic' that reads biblical sexual ethics as trajectory rather than exhaustive code, which opens space for nuanced conclusions.

Classical Islamic jurisprudence addresses masturbation more directly than either the Torah or the New Testament does, relying on Quranic verses about guarding one's private parts (Quran 23:5–7) and on hadith literature. The majority position among the four Sunni schools — Hanafi, Maliki, Shafi'i, and Hanbali — is that masturbation is haram (forbidden) or at minimum makruh (strongly discouraged). The Hanbali school, followed by scholars like Ibn Taymiyya (14th century), permits it in cases of necessity to avoid greater sin such as fornication.

Islamic scholars don't derive this ruling from the Torah directly, but they do regard the Torah (Tawrat) as an originally revealed scripture whose moral framework overlaps with Quranic ethics Deuteronomy 23:17. The Torah's prohibitions on sexual immorality and its concept of sexual holiness Deuteronomy 18:12 are seen as consistent with Quranic teaching, even if the specific rulings differ in detail. The Quran's own sexual legislation is considered the operative standard for Muslims.

Contemporary Muslim scholars such as Yusuf al-Qaradawi (The Lawful and the Prohibited in Islam, 1960) have maintained the general prohibition while acknowledging the minority permissive opinion. There's real scholarly disagreement here, and it's worth noting that no Quranic verse names masturbation explicitly — the prohibition is inferred, much as it is in Jewish and Christian tradition Deuteronomy 12:31.
