What Is the Difference Between Intentional Murder, Semi-Intentional Murder, and Pure Accidental Killing in Iranian Law?

Introduction

In criminal cases, many defendants are charged with “murder.” But are all murders legally the same?

According to Iranian law, there are three types of homicide:

Intentional murder (qatl-e amd)

Semi-intentional murder (qatl-e shibh-e amd)

Pure accidental killing (khatā-ye maḥz)

Each has distinct legal definitions and consequences. Understanding the difference is crucial, because the type of homicide determines the punishment.

This article explains these categories based on the Islamic Penal Code of Iran, in simple and clear terms.

What Is Intentional Murder?

Article 290 of the Islamic Penal Code states that murder is intentional when:

The act is committed with direct intent to kill,

Or the act is inherently lethal,

Or the perpetrator uses a deadly tool knowingly, even without specific intent to kill.

Examples:

Shooting someone in the head or chest

Stabbing someone in a vital area

Pushing someone from a tall building

In intentional murder, the main punishment is qisas (retribution by execution) — unless the victim’s family chooses to forgive or accept blood money (diya).

What Is Semi-Intentional Murder?

Article 291 defines semi-intentional murder as a case where:

The act itself is not lethal,

The offender does not intend to kill,

But death occurs due to the act or carelessness in using dangerous tools.

Examples:

A teacher slapping a student, who then suffers fatal trauma

A doctor prescribing the wrong medication

Hitting someone with a light object that accidentally causes death

In such cases, there is no qisas. The punishment is usually payment of diya and a prison sentence (ta’ziri).

What Is Pure Accidental Killing?

Article 292 states that killing is purely accidental (khata-ye maḥz) when:

The perpetrator has no intent to kill,

And no intent to harm,

The death occurs accidentally or unknowingly.

Examples:

A driver accidentally hits and kills a pedestrian without fault

A hunter shooting at an animal, accidentally hitting a person

Dropping an object from a height without knowing someone is below

In such cases, diya is mandatory but paid by the perpetrator’s male relatives (called ‘Aaqelah’). No prison sentence is typically imposed.

Summary Table of the Three Types of Homicide

The Role of Intent and Knowledge

To classify the type of homicide, the judge considers:

The actions and tools used

The mental state of the offender

The relationship between the parties

Medical reports and forensic evidence

Witness testimonies

️ In complex cases, the judge’s legal reasoning and forensic experts’ input are critical in determining the outcome.

Conclusion

Every case of homicide must be carefully assessed to determine whether it is intentional, semi-intentional, or purely accidental. This distinction significantly affects the type of punishment: execution, diya, or prison.
