Narrated Ibn `Umar: The Prophet burnt the date-palm trees of Bani An-Nadir. Hassan bin Thabit said the following poetic Verses about this event:-- "the terrible burning of Al-Buwaira Has been received indifferently By the nobles of Bani Luai (The masters and nobles of Quraish)." Abu Sufyan bin Al-Harith (i.e. the Prophet's cousin who was still a disbeliever then) replied to Hassan, saying in poetic verses:-- "May Allah bless that burning And set all its (i.e. Medina's) Parts on burning fire. You will see who is far from it (i.e. Al-Buwaira) And which of our lands will be Harmed by it (i.e. the burning of Al- Buwaira).
