Hadith 8:199
Abu Huraira reported God’s Messenger as saying, “One must not prevent his neighbour from fixing a beam in his wall.” (Bukhari and Muslim.)
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يَمْنَعْ جَارٌ جَارَهُ أَنْ يَغْرِزَ خَشَبَةً فِي جِدَاره»
