It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) had the trees of Banu Nadir cut down and set them on fire, and on that occasion Allah revealed the verse: "Whatever palm tree you cut down or left standing on its roots, it was by Allah’s command, and so that Allah may disgrace the defiantly disobedient."
