[Ruling on moving the soil of a waqf jarbah (agricultural plot) to another place]

Answer—and Allah is the One who grants success: What I have seen in a case like this, from the jurists of the madhhab as in the Commentary, is that if a branch is cut from a waqf tree and then planted, it is a waqf so long as it does not spoil.
I say: If the hill into which the jarbah’s soil was placed was a sanctuary/appendage of the original jarbah and its rightful adjunct, then the jarbah formed from the removed soil is waqf as a follower of the first waqf. Accordingly, it is not permissible to sell it; and this is the more precautionary view.
