Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ رُوِيَ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ شَجَرَةٌ أَصْلُهَا فِي اَلْحِلِّ وَ فَرْعُهَا فِي اَلْحَرَمِ فَقَالَ «حُرِّمَ أَصْلُهَا لِمَكَانِ فَرْعِهَا» قُلْتُ فَإِنَّ أَصْلَهَا فِي اَلْحَرَمِ وَ فَرْعَهَا فِي اَلْحِلِّ قَالَ «حُرِّمَ فَرْعُهَا لِمَكَانِ أَصْلِهَا».
It has been narrated from Mu'awiyah ibn Ammar, who said: I asked Abu Abdullah عليه السلام about a tree whose root is in the non-sacred area (hill) and its branches extend into the sacred area (Haram). Imam عليه السلام replied: "The root is sanctified because of the branch's location." I then asked: "What if its root is in the Haram and its branch extends into the hill?" Imam عليه السلام said: "The branch is sanctified because of the root's location."
