The accounts on the demise or martyrdom of Imam Ali Ibn Musa (PBUH) by various historians are different and sometimes contradictory. The prevalent and popular idea amongst the scholars from Imamiyyeh Jurisprudence School is that his highness has been poisoned and martyred by Ma’amun, Abbasids’ caliph. But, the Sunni historians and scientists have expressed different and conflicting notions in this regard. Some have proposed his highness’s extreme use of grape and some have opined his highness’s being poisoned by grape or pomegranate or pomegranate juice and some others have posited that his highness has been poisoned by Abbasids proponents and there are these others who speak of his highness’s natural death and there are still many others who state that his highness has been poisoned by Ma’amun. The present study is seeking to figure out the selected idea indicating his highness’s being poisoned based on a descriptive-analytical research method and through investigating and scrutinizing the various ideas mentioned in the resources and references of Sunni scholars and fellows.
