Ubayd Allah ibn Ziyad
Iranian scholar and politician Morteza Motahhari argued against this reasoning, stating that the Shia Imams' potential Sassanid ancestry would not have especially attracted Persians to Shi'ism. Noting that the mother of the Yazid III is believed to be a daughter of Peroz III, Motahhari added that the Persians had no equivalent inclination towards the Umayyad dynasty. Similarly, the Umayyad general Ubayd Allah ibn Ziyad is also not especially esteemed based on his maternal Persian heritage. In addition to this, Motahhari asserted that Shahrbanu is not venerated in Iran above the mothers of the other Imams, who came from a multitude of ethnic backgrounds, such as Narjis, who is believed to have been a Roman concubine.
