It is narrated on the authority of Ibn 'Umar (RA) that the Messenger of Allah (ﷺ) caused the date-palms of Banu Nadir to be cut down and burnt. It is in this connection that Hassan (the poet) said: It was easy for the nobles of Quraish to burn Buwaira whose sparks were flying in all directions. in the same connection was revealed the Qur'anic verse: "Whatever trees you have cut down or left standing on their trunks."
