It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) that there was a dispute between him and his brother Amr bin al-Zubayr. Abdullah bin al-Zubayr went in to Sa'id bin al-As while Amr bin al-Zubayr was sitting with him on the couch. Sa'id said to Abdullah: Come here (onto the couch). He said: No; rather, the judgement of the Messenger of Allah (peace and blessings be upon him) and his (peace and blessings be upon him) Sunnah is that both litigants sit (equally) before the judge. This hadith is sahih al-isnad (authentic in its chain), but the two Shaykhs (Bukhari and Muslim) did not record it.
