Answer:
On March 8, 1964, Malcolm X publicly announced his break with the Nation of Islam. He said he was still a Muslim, but that the Nation had arrived "as far as possible" due to its rigid religious teachings.Malcolm X announced that he was going to make a black nationalist organization that would try to "increase the political consciousness" of African-Americans. He also expressed his desire to work with other civil rights leaders and said that Elijah Muhammad had prevented him from doing so in the past.
In his autobiography, Malcolm X said that one of the reasons for the breakdown was the growing tension between him and Elijah Muhammad due to his dismay at Muhammad's rumors of extramarital affairs with young secretaries. These actions went against the teachings of the Nation. Although Malcolm initially ignored the rumors, he spoke with Muhammad's son and the women who made the accusations. He came to believe that it was true and Muhammad himself confirmed the rumors in 1963. Muhammad tried to justify his actions, referring to the precedents of the biblical prophets.
Another reason was envy, since Malcolm X had become the favorite of the media, and many at the Nation's headquarters in Chicago felt that it overshadowed Muhammad. Louis Lomax's book on the Nation of Islam of 1963, entitled "When the word is given", included a picture of Malcolm X on the cover and five of his speeches, but only one of Muhammad, which greatly upset Muhammad. Muhammad was also jealous because the publisher was interested in the autobiography of Malcolm X.
