[Machine] I was with Ali sitting when a man from the Banu 'Ijl tribe came, known as al-Mastawrid. He was a Muslim who converted to Christianity. Ali asked him, "What is that?" He replied, "I found their religion to be better than yours." Ali asked, "What is your religion?" He said, "The religion of Jesus, ﷺ ." Ali then said, "I am also upon the religion of Jesus, ﷺ . But what do you say about Jesus, ﷺ ?" He replied, "He said a word that was unclear to me, and the people claim that he said he is their Lord." Ali then said, "Kill him." The people attacked him until he died. Then the people of al-Hira came and gave him, meaning his corpse, twelve thousand coins, but Ali refused and ordered it to be burned. He did not take any of the money. This narration is also related by ash-Sha'bi and 'Abdul-Malik ibn 'Umayr from Ali but without mentioning the money. This narration has also been taken by ash-Shafi'i as evidence against his opponent Thabit but he apologized for using it, abandoning his argument based on the apparent saying of the Prophet ﷺ : "A Muslim does not inherit a disbeliever, nor does a disbeliever inherit a Muslim," just as Mu'adh and Mu'awiyah and others have left it in the matter of a Muslim inheriting from a Jew.
