During the siege of Banu Nadir, the famous tribe of the Jews in Madinah, some Muslims had cut down date-trees from around the fort to compel the enemy to surrender. After the war was over, some Jews objected to the cutting of the trees. The Holy Quran has answered the objection in the following words:
“Whatever date-trees you cut down, or left standing upon their roots, that was by the leave of Allah.” (59:5)
It has been very directly mentioned in this verse that the Muslims cut down the trees with a leave from Allah. But nobody can point out to any verse in the Holy Quran to the effect that the cutting of trees during the war is allowed. The question is: from where did the Muslims acquire this leave from Allah? There is no answer to this question except that the leave of Allah had been conveyed to them by the Holy Prophet (SAWS) and he received it through ‘unrecited revelation’.
