TL;DR: The Quran explicitly and repeatedly condemns riba (interest/usury), declaring it forbidden and warning of severe spiritual consequences. This is a question rooted in Islamic scripture, so Islam is the primary in-scope tradition. Judaism and Christianity have their own teachings on usury — often restricting it among community members — but they don't engage with the Quranic concept of riba directly. All three traditions share a general ethical concern about exploitative lending, though Islam's prohibition is the most absolute and legally developed. Quran 70:24

Judaism

Not applicable in the strict Quranic sense. The concept of riba as defined and prohibited in the Quran is specific to Islamic scripture and jurisprudence, with no direct Jewish counterpart term or ruling.

That said, Judaism does address interest-bearing loans. The Torah prohibits charging interest (neshekh) to fellow Israelites (Leviticus 25:36–37, Deuteronomy 23:20), though lending at interest to non-Israelites was permitted. The Talmud (Bava Metzia tractate) elaborates extensively on these rules. Medieval rabbinic authorities, including Maimonides (12th century), codified these restrictions in the Mishneh Torah. A legal workaround called the heter iska — a partnership agreement rather than a loan — was later developed to facilitate commercial lending within Jewish communities without technically violating the prohibition.

Christianity

Not applicable in the strict Quranic sense. The Quran's prohibition of riba is a distinctly Islamic scriptural and legal concept with no direct New Testament equivalent.

Christianity, however, has a long history of concern about usury. The Old Testament passages inherited by Christians (Exodus 22:25, Psalm 15:5) discourage charging interest to the poor. Early Church councils — including the Council of Nicaea (325 CE) — banned clergy from lending at interest. Medieval scholastics like Thomas Aquinas (13th century) argued that charging interest on money was intrinsically unjust because money itself is consumed in use. The Protestant Reformation, particularly John Calvin's writings in the 16th century, began to soften this stance, allowing moderate interest in commercial contexts. Modern mainstream Christianity generally does not prohibit interest outright, though concern for predatory or exploitative lending remains a live ethical issue.

Islam

وَٱلَّذِينَ فِىٓ أَمْوَٰلِهِمْ حَقٌّ مَّعْلُومٌ

The Quran's stance on interest — referred to as riba (literally 'increase' or 'excess') — is one of the most emphatic financial prohibitions in Islamic scripture. The condemnation appears across multiple surahs and escalates in severity across the Meccan and Medinan revelations.

The foundational prohibition appears in Surah Al-Baqarah (2:275–279), where Allah declares that those who consume riba 'will not stand except as one stands who is being beaten by Satan into insanity.' The verse famously draws a sharp contrast: 'Allah has permitted trade and has forbidden interest.' Verse 2:278–279 then issues a stark ultimatum to believers to abandon all remaining riba or face war from Allah and His Messenger — language that classical scholars like Al-Tabari (9th–10th century) and Ibn Kathir (14th century) considered among the most severe warnings in the entire Quran.

Surah Al-Imran (3:130) specifies the prohibition with additional detail Quran 70:24: 'O you who have believed, do not consume usury, doubled and multiplied, but fear Allah that you may be successful.' This verse targets the pre-Islamic Arabian practice of doubling a debt when a borrower couldn't repay on time — a compounding mechanism scholars like Yusuf al-Qaradawi (20th century) argue is the core evil riba seeks to eliminate.

Surah Ar-Rum (30:39) adds a spiritual-economic dimension, contrasting riba with charitable giving: interest may increase wealth in worldly terms, but it yields no increase with Allah, whereas charity does Quran 2:262.

Classical Islamic jurisprudence divided riba into two main categories: riba al-nasi'ah (interest on loans, the primary Quranic target) and riba al-fadl (unequal exchange of the same commodity, derived from hadith). All four major Sunni legal schools — Hanafi, Maliki, Shafi'i, and Hanbali — unanimously prohibit both forms, making this one of the rare points of total jurisprudential consensus (ijma').

In the modern era, Islamic finance has developed instruments like murabaha (cost-plus financing), ijara (leasing), and musharaka (profit-sharing partnerships) to enable commerce without riba. Scholars disagree, however, on whether bank interest in contemporary economies constitutes riba in every case — a debate that remains active among institutions like the Fiqh Academy of the OIC and individual scholars like Muhammad Taqi Usmani Quran 2:264.

Where they agree

Despite their different frameworks, all three traditions share a foundational ethical concern: exploitative lending that harms the vulnerable is morally wrong. Judaism restricts interest among community members to protect the poor. Christianity's long usury tradition, rooted in Aquinas and canon law, condemned profiting from another's need. Islam's riba prohibition targets the same exploitative dynamic. All three also affirm that generosity and charitable giving are spiritually superior to wealth accumulation — a value the Quran states explicitly in contrast to interest-taking Quran 2:262. The shared Abrahamic concern for economic justice across these traditions is striking, even if the legal conclusions differ significantly.

  • All four major Sunni legal schools unanimously prohibit riba, making it one of the most settled points of Islamic jurisprudence.
  • Judaism restricts interest among fellow Jews but permits it toward non-Jews; workarounds like the heter iska exist for commercial lending.
  • Christianity historically condemned usury through Church councils and scholastic theology, but modern mainstream Christianity generally permits moderate interest.
  • Islamic finance has developed an entire alternative financial industry — using murabaha, ijara, and musharaka — to enable commerce without violating the riba prohibition.

FAQs

What is riba in the Quran?
Riba literally means 'increase' or 'excess' in Arabic. The Quran uses it to describe any unjust addition to a loan or debt, most clearly targeting the pre-Islamic practice of doubling unpaid debts. Classical scholars like Ibn Kathir identified two main types: interest on loans (riba al-nasi'ah) and unequal exchange of goods (riba al-fadl). Quran 70:24
Does the Quran say interest leads to punishment?
Yes. Surah Al-Baqarah 2:275 compares those who consume riba to someone 'beaten by Satan into insanity,' and 2:279 warns of 'war from Allah and His Messenger' for those who refuse to abandon it. Ibn Kathir (14th century) called this one of the most severe warnings in the Quran. Quran 2:264
Is all interest haram in Islam, or just excessive interest?
The majority scholarly position — held by all four Sunni legal schools and bodies like the OIC Fiqh Academy — is that all interest on loans is prohibited, not just excessive rates. Surah Al-Imran 3:130 does mention 'doubled and multiplied' interest, but classical and modern scholars like Yusuf al-Qaradawi argue this describes the worst form, not the only prohibited form. Quran 70:24
How does Islamic finance avoid riba?
Islamic finance uses profit-and-loss sharing structures instead of fixed interest. Common instruments include murabaha (the bank buys an asset and resells it at a markup), ijara (leasing), and musharaka (equity partnership). These are designed to comply with the Quranic prohibition while enabling modern commerce. Quran 2:262
Did the Bible also prohibit interest?
The Hebrew Bible (Old Testament) restricts charging interest to fellow community members (Leviticus 25:36–37; Deuteronomy 23:20) but permits it toward outsiders. The New Testament doesn't explicitly prohibit interest, though early Church councils and medieval theologians like Thomas Aquinas extended the concern significantly. This is distinct from the Quranic prohibition of riba. Quran 70:24
