the Messenger of Allah ﷺ ruled concerning one, two or three date palms belonging to a man among other palm trees - when they differ concerning entitlement to the surrounding land. He ruled that the land around each of those trees, as far as their leaves reach, measured from the bottom of the tree, belongs to the owner of the tree. (Using translation from Ibn Mājah 2488)   

«قَضَى رَسُولُ اللَّهِ ﷺ فِي النَّخْلَةِ وَالنَّخْلَتَيْنِ وَالثَّلَاثِ فَيَخْتَلِفُونَ فِي حُقُوقِ ذَلِكَ فَقَضَى أَنَّ لِكُلِّ نَخْلَةٍ مُبْلَغَ جَرِيدِهَا حَرِيمًا»  

[Machine] Indeed, from the rulings of the Messenger of Allah ﷺ is that he ruled in regards to the single palm tree, the two palm trees, and the three palm trees, for a man who possessed palm trees and they disagreed regarding their rights. So he ruled that each palm tree should be given its full amount of dates. And in what Abu Dawood narrated in the Maraseel with his chain of narration from Uruwah ibn Zubayr, he said that the Messenger of Allah ﷺ ruled regarding the length of the palm tree's shade.  

إِنَّ مِنْ قَضَاءِ رَسُولِ اللهِ ﷺ أَنَّهُ قَضَى فِي النَّخْلَةِ وَالنَّخْلَتَيْنِ وَالثَّلَاثَةِ لِرَجُلٍ فِي نَخْلٍ فَيَخْتَلِفُونَ فِي حُقُوقِ ذَلِكَ فَقَضَى أَنَّ لِكُلِّ نَخْلَةٍ لِأُولَئِكَ مِنَ الْأَرْضِ مَبْلَغَ جَرِيدِهَا وَفِيمَا رَوَى أَبُو دَاوُدَ فِي الْمَرَاسِيلِ بِإِسْنَادِهِ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ قَالَ قَضَى رَسُولُ اللهِ ﷺ فِي حَرِيمِ النَّخْلِ طُولَ عَسِيبِهَا
