he said to al-Rida (a.s.) the following. “Amir al-Mu’minin Ali (a.s.) knew his assassin, the night in of being murdered and the spot whereat who be murdered. It is his words on hearing the ducks at the house, “These are the quacks that will be followed by lamentations.” Also the words of ’Umm Kulthum (his daughter). “Would that you pray inside the house and send someone else to lead the prayer in the Mosque.” He refused to do so and at that night he went many times out of the house unarmed. He knew that ibn Muljim, may he be condemned will murder him with a sword. He must not have exposed himself to it” The Imam (a.s.) said, “It is true but it was chosen that night wherein the measure and the determination of Allah, the Most Holy, the Most High would come to pass.”
