Is It Haram to Masturbate? What Judaism, Christianity, and Islam Teach

Classical Jewish law prohibits male masturbation under the category of hash-hatat zera — the 'wasting of seed' — derived from the narrative of Er and Onan in Genesis 38. The Talmud (Niddah 13a) treats the deliberate emission of semen outside of procreative intercourse as a serious transgression, and medieval authorities including Maimonides (12th century) codified this prohibition in the Mishneh Torah. The concern is rooted in the sanctity of procreation and the covenantal purpose of sexuality within marriage.

Modern Orthodox authorities such as Rabbi Moshe Feinstein generally upheld the prohibition, while some liberal Jewish movements (Reform, Reconstructionist) have moved away from treating it as a formal sin, emphasizing psychological health and personal autonomy. Female masturbation is treated far less stringently in classical sources, as no 'wasting of seed' is involved, though modesty norms still apply. The retrieved passage corpus does not contain directly applicable verses for this topic Jeremiah 33:18.

Christianity has no single canonical ruling on masturbation, but the dominant historical position across Catholic, Orthodox, and most Protestant traditions is that it is sinful. The Catholic Catechism (paragraph 2352, promulgated 1992) calls it 'an intrinsically and gravely disordered action' because it separates sexual pleasure from its procreative and unitive purposes within marriage. This position draws on natural law theology developed by Thomas Aquinas (13th century) and reinforced by Pope Paul VI's Humanae Vitae (1968).

Protestant traditions vary more widely. Reformers like John Calvin emphasized sexual purity broadly, and many evangelical theologians today treat masturbation as sinful when accompanied by lust, citing Matthew 5:28 ('whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart'). Some progressive Protestant scholars argue scripture is silent on the act itself. The retrieved passages touch on worship and service to God but do not address this topic directly Matthew 15:9.

The majority position among classical Islamic scholars — including the Shafi'i, Maliki, and Hanbali schools — holds masturbation to be haram (forbidden). The primary textual basis is Quran 23:5–7, which instructs believers to guard their private parts except with spouses or those whom their right hands possess, concluding that those who seek beyond this 'are the transgressors.' Imam Ahmad ibn Hanbal (9th century) and the majority of later scholars applied this verse to masturbation explicitly.

The Hanafi school holds a minority opinion that masturbation may be permissible (mubah) or even recommended (mustahabb) in cases where a person fears committing fornication (zina) and has no lawful means of relief — a position sometimes called the 'lesser of two evils' argument. Contemporary scholars such as Sheikh Yusuf al-Qaradawi have addressed this nuance extensively. The retrieved Arabic passages from the Quran in this corpus (Quran 28:11, 40:1, 20:117) do not address this topic Quran 28:11 Quran 40:1 Quran 20:117.
