Sahih al-Bukhari 4031
Narrated Ibn `Umar:
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)
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}‏
