It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When any of your neighbors asks permission to fix his beam in your wall, do not prevent him. When Hazrat Abu Hurairah (may Allah be pleased with him) narrated this hadith before the people, they began to raise their heads and look at him (as if they were surprised at this). Seeing this, Hazrat Abu Hurairah (may Allah be pleased with him) said: What is the matter that I see you turning away? By Allah, I will surely enforce it among your shoulders (i.e., implement it).
