وَعَنْهُ أَيْضًا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا ضَرَرَ وَلَا ضِرَارَ وَلِلرَّجُلِ أَنْ يَجْعَلَ خَشَبَةً فِي حَائِطِ جَارِهِ وَالطَّرِيقُ الْمِيتَاءُ سَبْعَةُ أَذْرُعٍ
It is also narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: (It is not permissible) to cause harm to your brother by diminishing his rights, nor is it permissible to cause greater harm than the harm received. And a person has the right to place a beam or the like on his neighbor’s wall, and the passageway for coming and going should be left at seven hands wide.
