[Machine] The Messenger of Allah ﷺ said: "When you dispute in a matter, make it (the path of disagreement) seven arms lengths and whoever builds a structure should support it with the wall of his neighbor."
قَالَ رَسُولُ اللهِ ﷺ إِذَا اخْتَلَفْتُمْ فِي الطَّرِيقِ فَاجْعَلُوهُ سَبْعَةَ أَذْرُعٍ وَمَنْ بَنَى بِنَاءً فَلْيَدْعَمْهُ بِحَائِطِ جَارِهِ
