Mus'ab bin Thabit says that there was some dispute between Sayyiduna Abdullah bin Zubair and his brother Amr bin Zubair. During this time, Sayyiduna Abdullah bin Zubair once went to Sa'id bin al-As. Amr bin Zubair was also sitting with him on the couch. Sa'id called him (Abdullah) closer as well, but he refused and said that the decision and Sunnah of the Prophet (peace be upon him) is that both parties should sit before the ruler.
