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»
"لَا ضَرَرَ وَلَا ضِرَارَ، وَلِلرَّجُلِ أَنْ يضَع حْشَبَةً في حَائِط جَارِهِ، وَالطَّرِيقُ المِيتَاءُ سَبْعَةُ أَذْرُعٍ".
