وَمَا كُنتَ بِجَانِبِ ٱلطُّورِ إِذْ نَادَيْنَا وَلَٰكِن رَّحْمَةًۭ مِّن رَّبِّكَ لِتُنذِرَ قَوْمًۭا مَّآ أَتَىٰهُم مِّن نَّذِيرٍۢ مِّن قَبْلِكَ لَعَلَّهُمْ يَتَذَكَّرُونَ
And thou was not beside the Mount when We did call; but (the knowledge of it is) a mercy from thy Lord that thou mayst warn a folk unto whom no warner came before thee, that haply they may give heed.

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)
