Imam Warith Deen Mohammed, popularly known as W. D. Mohammed, succeeded his father Elijah Muhammad in 1975, as leader of the Nation of Islam with unanimous support of its followers and began its transformation to the mainstream Islam.  He opened the Nation of Islam membership to all races of Muslims and encouraged Muslim Americans to register to vote and become full participants in the politics and economics of America. 

After Mohammed broke from the racial teachings of the Nation of Islam, Minister Louis Farrakhan broke away from Mohammed and formed his own separate group. While Farrakhan often got more media attention, Mohammed attracted a greater number of followers.

Farrakhan and Mohammed reconciled in 2000 through meetings and a joint public appearance at a Friday prayer in Chicago. However, still, Mohammed remained critical of many Nation of Islam leaders.

In 1977, Mohammed led the then largest delegation of Muslim Americans, most former members of the Nation of Islam, on Hajj, Pilgrimage to the Sacred House in Mecca, Saudi Arabia.  That same year he toured China with “American Friends of China”.

He also led a delegation of Muslim Americans to Jerusalem and areas under rule of the Palestinian Authority led by Palestinian leader, President Yasser Arafat, visiting Palestinian cities, government agencies, hospitals and homes throughout the West Bank.  The visit culminated on Christmas Eve with a meeting in Gaza City with President Arafat at his headquarters, where he discussed the difficulties of Palestinian life.

In 1997, President Clinton, in his re-election Inauguration, invited Imam Mohammed to the White House for the 1st Annual Ecuemnical Breakfast, and requested Imam Mohammed to read from the Holy Qur´an at the Presidential Inauguration Day National Prayer Service.

In 2000, he was appointed to the executive Committee of Religious Alliance Against Pornography (RAAP).

On September 11, 2001, Imam Mohammed, in the strongest terms, immediately denounced the terrorists attacks on the United States as un-Islamic and evil. 

The same year, Imam Mohammed attended the Contribution of Religions to Peace Conference in Assisi, Italy, at the invitation of Pope John Paul II, for religious leaders to gather to pray for world peace.

In 2002, he was ceremoniously inducted into the Martin Luther King Jr. International Board of Preachers at Morehouse College, in Atlanta, Georgia, where his portrait hangs in the International Chapel of Non-Violent Religious Leaders at Morehouse.
