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