The chief proof advanced by the jurists of Iraq is the ḥadīth of Abū Rāfiʿ, in which the Prophet—peace and blessings be upon him—said:

“ The neighbor has the strongest claim to pre-emption.”

This report is agreed upon. Al-Tirmidhī and Abū Dāwūd likewise relate—from the Prophet, peace and blessings be upon him—the saying:

“ The next-door neighbor has the greatest right to the house of his neighbor,”

and al-Tirmidhī judged it authentic. On rational grounds they add that, since the purpose of pre-emption is to remove the harm that may arise out of joint ownership, and since that same potential harm exists with an adjoining neighbor, the neighbor ought to share the right.

The scholars of Madinah reply: The harm found in co-ownership is greater than that found in mere adjacency.

In brief, the Mālikīs rely on the fundamental principle that no one’s property may be taken from his possession without his consent, and that what a person purchases remains his unless he willingly relinquishes it—unless a specific proof establishes an exception. Because the reports in this matter are contradictory, preference must be given to what is supported by first principles. Each opinion, moreover, has early precedent: among the people of Iraq from the Successors and among the people of Madinah from the Companions.

The Second Pillar: the property subject to pre-emption

Muslim scholars unanimously agree that pre-emption is obligatory in houses, real estate, and every kind of land, but they differ regarding other property.

Mālik’s doctrine may be summarized under three categories:

1. The principal category: immovable property itself—houses, shops, and orchards.

2. What is permanently attached to immovable property and cannot be moved or transferred, such as a well or the locations of palm-trees, so long as the underlying land remains jointly owned and undivided between the partners.

3. What is connected to that, such as fruit (about which there is disagreement), as well as the leasing of land for cultivation and the emancipation contract (kitāba) of a slave.

There is also disagreement reported from him regarding bathhouses and mills. As for other movable goods and livestock, he holds that no right of pre-emption applies to them, nor does it apply—according to him—to a pathway or to the open courtyard of a house.

Likewise, differing reports exist from him concerning the rental of dwellings, share-cropping arrangements, and debts: Does the debtor have the stronger claim? The same issue arises with respect to a slave under a kitāba contract, a view supported by ʿUmar ibn ʿAbd al-ʿAzīz.

It is narrated that the Messenger of Allah—peace and blessings be upon him—ruled for pre-emption in the case of a debt; this was also the opinion of Ashhab, one of Mālik’s students. Ibn al-Qāsim, however, said, “There is no pre-emption in debt.” Yet the two of them did not differ about its obligation in the case of a kitāba contract, because of the sanctity of manumission.
