Since he had heard 'Ali (a) was using henna for dying his beard, he quoted from Torah, “Whosoever dyes his beard black is cursed”. [^5]2707 The Umayyads' agents used abusive words towards 'Ali's family throughout the Islamic land [^6] to taint their reputation and eliminate them from political as well as intellectual scene by rendering the worst accusations against them. That was why harsh treatment in damning 'Ali was quite justified for them.
Once Hajjaj asked his governor in Fars to make 'Atiyya Ibn Sa'd damn 'Ali (a) and if avoided doing so, he should be whipped four hundred times and be shaved as punishment.
They did this as Hajjaj had ordered.[^7] Some individuals as Ibn Abi Layla, an Iraqi jurisprudent, was made to curse 'Ali (a) in public.[^8]2710 It was quite common for Mu'awiya, Abu Bakr as well as 'Umar to fabricate Hadith to crush Shi'ite Muslims who were referred Rafiďi extremist and now most of those forged traditions compiled by the Sunnites are at hand.[^9]2711 When Hisham in 106 A.H., the second year of his caliphate, entered Hijaz for Hajj, Medina's governor, one of 'Uthman's grand children, by alluding to 'Uthman's virtues told caliph, “In this region, it is quite common to curse Abu Turab, now you can follow this custom too”.
Hisham in reply said, “Now I am here for Hajj and do not intend to curse anyone.”[^10]2712 This does not mean that Hisham was not a man of cursing others. In contrast all of his deeds revealed his hostility towards the Prophet's Household and their followers. He himself was the murderer of Zayd Ibn 'Ali and any Shi'ite Muslims and under those circumstances, he probably gave such reply to Sa'id Ibn 'Abd Allah for a specific reason.
When Zayd Ibn 'Ali (a) was in Damascus, Hisham shamelessly inquired him about his brother, Imam as-Sadiq (a) and said, مافعل اخوك البقرة In this way, he demonstrated his malice towards him in his insulting question. In response, Zayd said, سماه رسول الله باقراً وتسميّة البقرة!
لقد اختلفتما اذاً [^11] “The Messenger of Allah had called him al-Baqir and now you are addressing him in this way.” Then he went on to say Jabir's quotation in which Allah's Messenger had told him, “Give Imam al-Baqir my best regards.” Shi'ite Muslims such as Kumayt Ibn Zayd Asadi, an outstanding Arab poet, were pressurized in various forms. He was imprisoned for his beliefs and, in particular, having Khalid Ibn 'Abd Allah Qasri satirizing the Umayyads.
