Islamic Contract Law: Classification of Ownership According to Its Substance

Ownership (milkiyyah) can be classified according to how much of the property a person actually owns.

In terms of substance, ownership is divided into two main types:

1. Complete ownership (al-milk al-tamm)
2. Deficient ownership (al-milk al-naqis)

1. Complete Ownership (

Al-Milk al-Tamm

)

Al-milk al-tamm means complete or full ownership.

The owner has rights over both:

• The physical property itself (‘ayn)
• The benefit or usufruct (manfa‘ah) of the property

This gives the owner broad authority to use and deal with the property, as long as the use is permitted by Shariah.

Rights of a Complete Owner

The owner may generally:

• Use the property
• Live in it
• Rent it out
• Sell it
• Give it as a gift
• Donate it
• Transfer ownership to another person

Example

Ahmad owns a house and lives in it.

He owns:

• The house itself = ‘ayn
• The benefit of living in it = manfa‘ah

Therefore, Ahmad has:

Complete ownership (al-milk al-tamm)

Another Example

Fatimah owns a car.

She owns the physical car and also has the right to use it.

She may:

• Drive it
• Rent it
• Sell it
• Give it away

Therefore, her ownership is complete.

Easy Meaning

Complete ownership = ownership of both the asset and its benefit.

2. Deficient Ownership (

Al-Milk al-Naqis

)

Al-milk al-naqis means incomplete, limited, or deficient ownership.

In this type of ownership, a person does not have full rights over both the physical property and its benefit.

Instead, the person may have a right over:

• The physical property (‘ayn) only, or
• The usufruct or benefit (manfa‘ah) only

Therefore, the person’s control is limited.

Example: Ownership of

Manfa‘ah

Only

Ahmad owns a house and rents it to Ali for one year.

During the lease:

• Ahmad remains the owner of the house itself.
• Ali receives the right to live in and use the house for one year.

Ali does not own the physical house.

He only has the manfa‘ah.

Therefore, Ali has a form of:

Deficient ownership

because he owns or controls only the benefit, not the physical asset.

Example: Ownership of the Physical Asset While Another Person Has the Benefit

Suppose Ahmad owns a house but has rented it to Ali.

Ahmad still owns the:

Physical house (‘ayn)

However, during the rental period, Ali has the:

Right of use (manfa‘ah)

Ahmad cannot simply occupy the house during the rental period because the benefit has been transferred to Ali.

So Ahmad’s immediate rights over the property are restricted for the duration of the lease.

This illustrates how ownership of the asset and ownership of its benefit can be separated.

Main Difference

Complete Ownership

The person owns:

‘Ayn + Manfa‘ah

Example:

Ahmad owns and uses his own house.

Deficient Ownership

The person owns or controls:

Only ‘ayn

or

Only manfa‘ah

Example:

A tenant has the manfa‘ah of a rented house but does not own the house itself.

Why Is It Called “Deficient” Ownership?

The word deficient does not mean the ownership is invalid.

It simply means that the person does not have all the rights that a complete owner would have.

The ownership is limited to only one part of the property relationship.

For example, a tenant lawfully has the right to live in the property, but the tenant cannot usually:

• Sell the house
• Give the house away
• Claim permanent ownership

This is because the tenant owns only the benefit, not the physical property.

Simple Summary

Complete Ownership —

Al-Milk al-Tamm

The owner has rights over:

• Physical property (‘ayn)
• Benefit (manfa‘ah)

Example:

Owner of a house who also has the right to use it

Deficient Ownership —

Al-Milk al-Naqis

The person has rights over:

• The physical property only, or
• The benefit only

Example:

Tenant who has the right to live in a rented house but does not own the house

Easy Way to Remember

Complete ownership = ‘ayn + manfa‘ah

Deficient ownership = only ‘ayn or only manfa‘ah
