مَا قَطَعْتُم مِّن لِّينَةٍ أَوْ تَرَكْتُمُوهَا قَآئِمَةً عَلَىٰٓ أُصُولِهَا فَبِإِذْنِ ٱللَّهِ وَلِيُخْزِىَ ٱلْفَٰسِقِينَ
Whatsoever palm-trees ye cut down or left standing on their roots, it was by Allah's leave, in order that He might confound the evil-livers.
Surah Al-Hashr(59:5)
Sahih al-Bukhari
Virtues of Madinah
Chapter: Haram (sanctuary) of Al-Madina
Narrated Anas:
The Prophet (ﷺ) came to Medina and ordered a mosque to be built and said, "O Bani Najjar! Suggest to me the price (of your land)." They said, "We do not want its price except from Allah" (i.e. they wished for a reward from Allah for giving up their land freely). So, the Prophet (ﷺ) ordered the graves of the pagans to be dug out and the land to be leveled, and the date-palm trees to be cut down. The cut datepalms were fixed in the direction of the Qibla of the mosque.
