Sunan Ibn Majah, Volume 3, Book 16, Hadith 2488 (DarusSalam) ⓘ

It was narrated from 'Ubadah bin Samit that : the Messenger of Allah 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.

حَدَّثَنَا عَبْدُ رَبِّهِ بْنُ خَالِدٍ النُّمَيْرِيُّ أَبُو الْمُغَلِّسِ، حَدَّثَنَا الْفُضَيْلُ بْنُ سُلَيْمَانَ، حَدَّثَنَا مُوسَى بْنُ عُقْبَةَ، أَخْبَرَنِي إِسْحَاقُ بْنُ يَحْيَى بْنِ الْوَلِيدِ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَضَى فِي النَّخْلَةِ وَالنَّخْلَتَيْنِ وَالثَّلاَثَةِ لِلرَّجُلِ فِي النَّخْلِ فَيَخْتَلِفُونَ فِي حُقُوقِ ذَلِكَ فَقَضَى أَنَّ لِكُلِّ نَخْلَةٍ مِنْ أُولَئِكَ مِنَ الأَرْضِ مَبْلَغُ جَرِيدِهَا حَرِيمٌ لَهَا ‏.‏
