وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم - قَالَ: { لَا يَمْنَعُ جَارٌ جَارَهُ أَنْ يَغْرِزَ خَشَبَةً فِي جِدَارِهِ . ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ - رضى الله عنه - مَا لِي أَرَاكُمْ عَنْهَا مُعْرِضِينَ? وَاَللَّهِ لَأَرْمِيَنَّ بِهَا بَيْنَ أَكْتَافِكُمْ } مُتَّفَقٌ عَلَيْهِ [1] .
Narrated Abu Hurairah (RA): The Prophet (ﷺ) said: "One must not prevent his neighbor from fixing a wooden peg in his wall." Abu Hurairah (RA) then said, "Why do I see you turning away (averse to this Sunnah)? I swear by Allah that I will always narrate it to you." [Agreed upon].
