Ibn-e-Ziyaad And Qisas-e-Hussain (rta)
When such kind of case happens even today a committee is appointed to investigate all the facts. The history did not record the viewpoint of Ibn ziyaad and Ibn e Saad. In politics ideal measures are taken but possible and appropriate measure are taken. There is no compaign for Husain against Banu Ummayya except for a short one, of Tawwabeen. Alwi aspirants used their lineage as a merit to claim caliphate. It was Banu Abbas who defeated Banu umayyah. The main factor in their success was non Arabs who wanted Alwis to be caliphs as a political party of theirs and ensure their stake in the government.
