Is it permissible to cut down or burn enemy trees and crops outside of military necessity?

Primary text

The ruling on destroying vegetation is divided into three categories. First, destruction is permissible without known dispute if necessitated by military needs, such as clearing areas near forts, destroying cover, widening roads, providing cover for a catapult, or if the enemy employs similar tactics against Muslims. Second, destruction is forbidden if it causes harm to Muslims, such as destroying their source of fodder or shade. Third, if destruction serves only to grieve the enemy without direct benefit or harm to Muslims, there are two narrations. The view upholding prohibition cites Abu Bakr's advice against such destruction and deeming it mere, unjustified waste (*itlaf*), supported by Al-Awza'i, Al-Layth, and Abu Thawr.
