The Holy Quran 59:5 — Surah Al-Hashr
Arabic text
مَا قَطَعْتُم مِّن لِّينَةٍ أَوْ تَرَكْتُمُوهَا قَآئِمَةً عَلَىٰٓ أُصُولِهَا فَبِإِذْنِ ٱللَّهِ وَلِيُخْزِىَ ٱلْفَـٰسِقِينَ
Translation
(Referring to the date plantations of the Banu Nadheer that the Muslims destroyed to break the morale of the Jews for them to surrender, Allaah says,) Every date palm that you (Muslims) cut (and burnt) or left standing on its roots was by Allaah's permission and to humiliate the sinners. (It was done by Allaah's command and not merely to destroy property.)
Tafsir (excerpt) — Tafsir Usmani
The Muslims cut down the trees: that is, when those people shut themselves up in their fortresses, the Prophet ﷺ gave permission for their trees to be cut down and their orchards laid waste, so that, pained by this, they would be forced to come out and fight, and so that the trees would no longer be an obstacle at the time of open battle.
