One Who Builds Something On His Own Property That Harms His Neighbor — Sunan Ibn Majah 2340

Overview & Central Theme

This foundational legal maxim, “Lā ḍarar wa lā ḍirār” (لا ضرر ولا ضرار), establishes the absolute prohibition of causing harm to oneself or others, whether initially or in retaliation. It serves as a comprehensive principle in Islamic jurisprudence (fiqh) that underpins rulings on property, contracts, family, and public welfare. The hadith, transmitted in Sunan Ibn Majah 2340 within “The Chapters on Rulings,” encapsulates the Shariah’s overarching objective of preserving individual and communal well-being, ensuring that no action—whether deliberate or negligent—inflicts injury, and that reciprocal harm is equally forbidden. This principle is a cornerstone of Islamic social justice, balancing rights with responsibilities and promoting harmony over vengeance.

Context & Linguistic Insights

The hadith was reportedly pronounced by the Prophet ﷺ in the context of a dispute over land irrigation, where a man sought to block water flow, harming his neighbor. The Prophet ﷺ ruled against the harm, establishing this universal maxim. Linguistically, “ḍarar” (ضرر) refers to initial harm or injury, while “ḍirār” (ضرار) denotes reciprocating harm or harm intended as retaliation. Scholars like Ibn al-Athir note that “ḍirār” implies harm done in response to harm, which is equally prohibited, thus closing the door to cycles of vengeance. The negation “lā” is understood as a prohibition (nahy), making both acts unlawful. This distinction emphasizes that even in disputes, one may not inflict damage merely because harm was received; instead, justice must be sought through lawful means. The phrase is also seen as a legislative principle (qā‘idah fiqhiyyah), widely cited in legal manuals to resolve novel issues, from property damage to digital privacy.

Key Scholarly Insights & Legal Benefits

• Prohibition of Harm: This hadith establishes that causing any form of harm—physical, financial, psychological, or environmental—is impermissible, and the state or judiciary may intervene to remove such harm.
• No Retaliation with Harm: Even if one is wronged, responding with harm is forbidden; the injured party must seek redress through lawful channels, preserving social order and preventing escalation.
• Foundation for Legal Maxims: Scholars derived subsidiary principles, such as “Harm must be eliminated” (al-ḍarar yuzāl) and “Necessity permits prohibited acts” (al-ḍarūrāt tubīḥ al-maḥẓūrāt), which are applied in contemporary jurisprudence, including medical ethics and contract law.

Imam Ibn Rajab al-Hanbali commented: “This hadith is one of the great principles of Islam. Upon it are built many rulings, and it is a comprehensive basis for preventing injustice and ensuring that no one’s rights are violated, whether in small or large matters.”

Daily Life & Spiritual Application

In daily life, this teaching demands mindfulness in every interaction: avoid harming neighbors through noise, property damage, or encroachment; refrain from financial harm in business transactions, such as fraud or hoarding; and guard against emotional harm through harsh words or gossip. Spiritually, it cultivates a character of compassion and restraint, recognizing that true strength lies in forgiving rather than retaliating. When faced with injustice, a Muslim is encouraged to seek lawful remedies while maintaining inner peace, trusting that Allah is the ultimate Just Judge. This principle also extends to self-care—one must not harm one’s own body or soul through negligence or sin. By embodying “no harm, no reciprocating harm,” believers contribute to a society rooted in mutual respect, mercy, and justice, reflecting the Prophetic mission as a mercy to all worlds.
