the Messenger of Allah ﷺ said, "There should be no causing of harm or reciprocation of harm. A person is allowed to fix a wooden peg in the wall of his neighbor, and the width of a public pathway is seven cubits."  

قَالَ رَسُولُ اللهِ ﷺ لَا ضَرَرَ وَلَا ضِرَارَ وَلِلرَّجُلِ أَنْ يَجْعَلَ خَشَبَةً فِي حَائِطِ جَارِهِ وَالطَّرِيقُ الْمِيتَاءُ سَبْعَةُ أَذْرُعٍ  

[Machine] The Prophet ﷺ said: "There should be no harming or reciprocating harm. A person should secure a piece of wood on the wall of his neighbor. And if you have doubts about the road, then make it seven cubits."  

أَنَّ النَّبِيَّ ﷺ قَالَ «لَا ضَرَرَ وَلَا ضِرَارَ وَلِلرَّجُلِ أَنْ يَجْعَلَ خَشَبَةً عَلَى حَائِطِ جَارِهِ وَإِذَا شَكَكْتُمْ فِي الطَّرِيقِ فَاجْعَلُوهَا سَبْعَةَ أَذْرُعٍ»
