Sahih al-Bukhari, Hadith 4031 ⓘ

Narrated Ibn `Umar: Allah's Messenger had the date-palm trees of Bani Al-Nadir burnt and cut down at a place called Al- Buwaira. Allah then revealed: "What you cut down of the date-palm trees (of the enemy) Or you left them standing on their stems. It was by Allah's Permission." (59.5)
