Sunan An-Nasa'i

It was narrated that 'Abdur-Rahman bin Muhairiz said:""I said to Fadalah bin 'Ubaid: 'Do you think that hanging the hand from the thief's neck is Sunnah?' He said: 'Yes; a thief was brought to the Messenger of Allah and he cut off his hand and hung it from his neck.""' (Daif) Abu 'Abdur-Rahman (An-Nasai) said; Al-Hajjaj bin Artah is weak, his narrations are not used as proof
