Narrated Sa`id bin Jubair: I asked Ibn `Abbas about Surat Al-Tauba, and he said, "Surat Al-Tauba? It is exposure (of all the evils of the infidels and the hypocrites). And it continued revealing (that the oft-repeated expression): '...and of them ...and of them.' till they started thinking that none would be left unmentioned therein." I said, "What about) Surat Al-Anfal?" He replied, "Surat Al-Anfal was revealed in connection with the Badr Battle." I said, "(What about) Surat Al-Hashr?" He replied, "It was revealed in connection with Bani an-Nadir."

Narrated Sa`id: I asked Ibn `Abbas about Surat Al-Hashr. He replied, "Say Surat An-Nadir."

Narrated Ibn `Umar: 'Allah's Messenger burnt and cut down the palm trees of Bani An-Nadir which were at Al-Buwair (a place near Medina). There upon Allah revealed: 'What you (O Muslims) cut down of the palm trees (of the enemy) or you left them standing on their stems, it was by the leave of Allah, so that He might cover with shame the rebellious.' (59.5)

Narrated `Umar: The properties of Bam An-Nadir were among the booty that Allah gave to His Apostle such Booty were not obtained by any expedition on the part of Muslims, neither with cavalry, nor with camelry. So those properties were for Allah's Messenger only, and he used to provide thereof the yearly expenditure for his wives, and dedicate the rest of its revenues for purchasing arms and horses as war material to be used in Allah's Cause.
