Is a usurper liable for damage that diminishes the value of usurped property?

Primary text

The usurper is liable for any permanent diminution in the value of the usurped property, whether the damage is caused by planting on the land, or by other means. This applies to all usurped items, such as a torn garment, a broken vessel, spoiled food, or a ruined building. The usurper must return the item along with the compensation (*arsh*) for the damage sustained while it was in his possession. This principle is established by analogy to similar fixed quantities, such as a measure of food or a length of cloth. This is the position held by Al-Shafi'i.
