Shahadat of Imam Ali Reza
Imam Ali Reza (a.s) was martyred on 17th Safar, 819 AH. Mamun (la) asked the Imam to come to leave the city of Marw and asked him to come to Mashad. Once he had arrived there, Mamum offered him first the caliphate and then the succession to the caliphate. Imam Reza (a.s) turned down the proposal, but he was forced into accepting the offer, with the condition that he would not interfere in governmental affairs.
Mamun decided to do this because he wanted to be accepted by the Shias and rule over the country. Imam (a.s) had to leave his family behind in Medina in order to fulfill this role. Even though Imam did not want to take this position, he made full use of it to preach Islam openly. Imam often acted as Mamun’s advisor. Mamun had even changed the colour of his court from black to green and also had new coins made with Imam Ali Reza (a.s) name on it upon his request. Mamun’s sister Umm Habiba was married to the Imam, this did not change the Imam’s or the Shia’s view of Mamun.
Soon, Mamun realized that he had made a mistake because there was a rapid spread of Shiaism and more attachment towards Imam Reza (a.s). Mamun wanted to find a solution for this problem and decided put poison into pomegranates (some books say grapes) and presented it to Imam Reza (a.s) and after only a few hours the poison polluted Imam’s body and he became ill. The next day, Imam Reza (a.s) was martyred in the city of Mashhad, Iran far away from his family.
