Bisme Ta’ala
When Ameerul Momineen (a.s.) learnt that they blame him for what is narrated about the precedence of Messenger of Allah (s.a.w.a.) in praising him and they dispute about his Caliphate, he was present among people in Rahba (An open space in front of the mosque where Imam Ali would deliver his sermons and judge cases) in Kufa. He challenged those, who disputed the matter of his Caliphate through the tradition of Ghadeer.
Such is the importance of this reasoning and challenge that a large number of companions of companions have mentioned it and it is quoted in books of numerous scholars. I (Allama Amini r.a.) have found it in the statements of four companions and fourteen companions of companions. Among them is Abu Sulaiman Muezzin, Abul Qasim Asbagh bin Nubata, companion Zaid bin Arqam Ansari.
Ibne Abil Hadeed in Sharh Nahjul Balagha, has through his authorities narrated from Abu Sulaiman Muezzin. Ali (a.s.) adjured the people: “Which of you have heard from the Messenger of Allah (s.a.w.a.): Of whomsoever I am the master, Ali is also his master?” A group of people replied in positive, but Zaid bin Arqam, in spite of knowing, refrained from responding and Ali (a.s.) cursed him to become blind, thus he became blind and after his blindness, he mentioned this tradition to people.
