Abd Allah ibn al-Zubayr
In Medina, Mu'awiya's distant kinsmen Marwan ibn al-Hakam, Sa'id ibn al-As and Ibn Amir accepted Mu'awiya's succession order, albeit disapprovingly. Most opponents of Mu'awiya's order in Iraq and among the Umayyads and Quraysh of the Hejaz were ultimately threatened or bribed into acceptance. The remaining principle opposition emanated from Husayn ibn Ali, Abd Allah ibn al-Zubayr, Abd Allah ibn Umar and Abd al-Rahman ibn Abi Bakr, all prominent Medina-based sons of earlier caliphs or close companions of Muhammad. As they possessed the nearest claims to the caliphate, Mu'awiya was determined to obtain their recognition. According to Awana ibn al-Hakam (d. 764), before his death, Mu'awiya ordered certain measures to be taken against them, entrusting these tasks to his loyalists al-Dahhak ibn Qays and Muslim ibn Uqba.
