Hadith 10:1287
Abu Bakr narrated to us, he said: Mu'tamir narrated to us, from Layth, from Tawus, regarding the two arbitrators: When they judge, accept their judgment and do not follow the trace of anyone else, even if someone had judged against you before them.
حدثنا أبو بكر قال نا معتمر عن ليث عن طاوس في الحكمين إذا حكما فخذ بحكمهما ولا تتبع أثر غيرهما وإن كان قد حكم قبلهما عليك
