Sahih al-Bukhari · Book 64: Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi) · The story of Bani An-Nadir
Narrated Ibn `Umar:
حَدَّثَنَا آدَمُ ، حَدَّثَنَا اللَّيْثُ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ حَرَّقَ رَسُولُ اللَّهِ صلى الله عليه وسلم نَخْلَ بَنِي النَّضِيرِ وَقَطَعَ وَهْىَ الْبُوَيْرَةُ فَنَزَلَتْ {مَا قَطَعْتُمْ مِنْ لِينَةٍ أَوْ تَرَكْتُمُوهَا قَائِمَةً عَلَى أُصُولِهَا فَبِإِذْنِ اللَّهِ}
Allah's Messenger (ﷺ) had the date-palm trees of Bani Al-Nadir burnt and cut down at a place called Al- Buwaira. Allah then revealed: "What you cut down of the date-palm trees (of the enemy) Or you left them standing on their stems. It was by Allah's Permission." (59.5)
