Shufa in Islam
The right of shufaa or pre-emption is a right, which the owner of an immovable property possesses to acquire by purchase another immovable property, which has been sold to another person. The law of pre-emption imposes a limitation or disability upon the ownership of property to the extent that it restricts the owner’s unfettered right of transfer of property and compels him to sell it to his co-heir or neighbor, as the case may be. He person, who is a co-sharer in the property, or owes property in the vicinity, gets an advantage corresponding to the burden with which the owner of the property is saddled, even though it does not amount to an actual interest in the property.
