The Supervisors and the Assistants in the Assassination of the Commander of the Faithful (a.s)

In the month of Ramadhan, 40th A. H, one of the most painful incidents of Shia's history took place in the mosque of Koofah. That day, Abdurrehman-ibne-Muljam Muradi, the one whom the holy Prophet (PBUHH) has called as «the most wretched person among the slaves of Allah», drew a deep cut in the head of the best person on the earth, with his poisoned sword. It was not the sword of Ibne-Muljam, but the sword of ignorance and animosity of Khawarij which colored the beard of the Commander of the Faithful (a. s) with his holy blood amid the sanctuary of the Mosque of Koofah, at the time of the Morning Prayer of 19th Ramadhan.
After the season of Hajj in 39 A. H, Ibne-Muljam concluded an agreement with two other Khawarijis, who were also dissatisfied from the consequences of the matter of arbitration in the war of Siffeen, to slain down Muaviyyah, Amr-al-Aas and Ali (a. s) on a particular day; however the companions of Ibne-Muljam remained failed in their attempts.
Ibne-Muljam, after entering the city of Koofah in the month of Shaaban, 40 A. H, visited the Khawarijis of this city and stayed in the house of Ashas-ibne-Qais who was one of the heads of Khawarij, where he falls in love with Qutam after being introduced with her, whereas she also demands the murder of the Commander of the Faithful (a. s) as her marriage portion.
In this crime, various persons have aided Ibne-Muljam whereas this writing discloses the role of each of them and reveals its whole process of happening.
