Abu Dawud Book 36, Hadith Number 5155.

Chapter : Not known.

Narated By Huzayl : A man came. Uthman’s version has: Sa’d ibn AbuWaqqas came. He stood at the door. Uthman’s version has: (He stood) facing the door. The Prophet (PBUH) said to him: Away from it, (stand) this side or that side. Asking permission is meant to escape from the look of an eye.
