Not only was al-Zuhri working for the Umayyad government, but both Sa‘īd (Sharh Nahj al-Balāgha, vol. 4, pg. 101.) and Mughīra (Al-Aghānī, vol. 17, pg. 90; al-Kāmil fi al-Tārīkh, vol. 3, pg. 430.) were recognized for their reservations against Imam ‘Ali (a). How is it then possible to accept these reports without any further investigation? these narrators were openly hostile to Imam ‘Ali and the entire clan of Bani Hashim, could there be a conflict of interest?
