Riyad as-Saliheen 307
Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "No one should prohibit his neighbour from placing a peg in his wall". Abu Hurairah (May Allah be pleased with him) added: Now I see you turning away from this (Sunnah), but by Allah, I shall go on proclaiming it.
[Al-Bukhari and Muslim].
وعنه أن رسول الله ﷺ قال:
" لا يمنع جار جارة أن يغرز خشبة في جداره" ثم يقول أبو هريرة: ما لي أراكم عنها معرضين! والله لأرمين بها بين أكتافكم. ((متفق عليه)).
