Abu Da'ud أبو داود السجستاني الأزدي · The Office of the Judge (Kitab Al-Aqdiyah)

When one of you asks permission for inserting a wooden peg in his wall, he should not prevent him. So they (the people) lowered down their heads. Then he (Abu Hurairah) said: What is the matter ? I am seeing you are neglecting (to hear this tradition), I shall spread it among you. Abu Dawud said:This is the tradition of Ibn Abi Khalaf is more perfect.
