Is it permissible to sell materials used to build structures in Mecca that were brought from outside the Haram boundaries?

Primary text

The sale of materials brought from outside the boundaries of Mecca to construct a building within Mecca is permissible. This ruling is analogous to the permissibility of selling structures designated as endowments (*Waqf*) and the debris from them. The permissibility of selling structures built using soil and stones from the Haram boundaries depends on the two established narrations concerning the sale of properties (*Rubu'*) within Mecca, as these properties are considered subservient to Mecca itself. This principle extends to the soil and debris of every endowment.
