مَا قَطَعۡتُم مِّن لِّينَةٍ أَوۡ تَرَكۡتُمُوهَا قَآئِمَةً عَلَىٰٓ أُصُولِهَا فَبِإِذۡنِ ٱللَّهِ وَلِيُخۡزِيَ ٱلۡفَٰسِقِينَ ٥
Whatever you have cut down of [their] palm trees or left standing on their trunks - it was by permission of Allāh and so He would disgrace the defiantly disobedient.
Translation: Saheeh International (English)
Each word's meaning and sound
O believers! Whatever date palm you cut down to infuriate the enemies of Allah in the battle of the Banū an-Naḍīr, or you left it standing with its trunk to make use of it, was done with the command of Allah; it was not done to cause destruction on earth like they claimed. It was also done so that Allah could humiliate through it those who left the obedience of Allah from the Jews: those that broke the treaties and chose the path of treason over the path of loyalty.
