Imam Hassan died in Medina, most likely from poisoning, although some accounts suggest illness.
While the exact cause of death remains debated, the prevailing historical narrative, particularly among early sources, points towards poisoning as the primary reason. Many believe that Mu'awiya, a political rival, orchestrated the poisoning to clear the path for his son, Yazid I, to succeed him. This would remove Imam Hassan as a potential contender for leadership. The sources do not agree on who administered the poison, with some accounts implicating his wife, Ja'da bint al-Ash'ath, at the instigation of Mu'awiya.
It's important to acknowledge the alternate view suggesting death by illness. However, the significant consensus among early historical records emphasizing poisoning leads most scholars to favor that explanation.
