It is narrated on the authority of 'Abdullah that the Messenger of Allah (may peace be upon him) ordered the date-palms of Banu Nadir to be burnt and cut. These palms were at Buwaira. Qutaibah and Ibn Rumh in their versions of the tradition have added: So Allah, the Glorious and Exalted, revealed the verse:" Whatever trees you have cut down or left standing on their trunks, it was with the permission of Allah so that He may disgrace the evil-doers" (lix. 5).
