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 one of you asks his neighbor for permission to fix a beam in his wall, he should not prevent him. When Hazrat Abu Hurairah (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 Hurairah (may Allah be pleased with him) said: What is the matter that I see you turning away? By Allah, I will certainly enforce this among your shoulders (i.e., I will implement it among you).
