Muhammad (c. 26 April 570 – 8 June 632; also transliterated as Mohammad, Mohammed, or Muhammed; Arabic: محمد‎), full name: Muhammad Ibn `Abd Allāh Ibn `Abd al-Muttalib (Arabic: محمد بن عبدالله بن عبد المطلب ‎) was a leader from Mecca who unified the tribes of Arabia into a single religious polity under Islam. He is believed by Muslims and Bahá'ís to be a messenger and prophet of God. Muslims believe that Islam was not his own invention but was revealed by God, and most consider him to be the last prophet of God Muslims thus consider him the restorer of an uncorrupted original monotheistic faith (islām) of Adam, Noah, Abraham, Moses, Jesus and other prophets.

Born in 570 CE in the Arabian city of Mecca, he was orphaned at an early age and brought up under the care of his uncle Abu Talib. He later worked mostly as a merchant, as well as a shepherd, and was first married by age 25. Being in the habit of periodically retreating to a cave in the surrounding mountains for several nights of meditation and prayer, he later reported that it was there, at age 40, that he received his first revelation from God. Three years after this event Muhammad started preaching these revelations publicly, proclaiming that "God is One", that complete "surrender" to Him (lit. islām) is the only way (dīn) acceptable to God, and that he himself was a prophet and messenger of God, in the same vein as other Islamic prophets.

Muhammad Ali (born Cassius Marcellus Clay, Jr.; January 17, 1942) is an American former professional boxer, philanthropist and social activist. Considered a cultural icon, Ali was both idolized and vilified.

Originally known as Cassius Clay, Ali changed his name after joining the Nation of Islam in 1964, subsequently converting to Sunni Islam in 1975, and more recently practicing Sufism.^{[clarification needed]} In 1967, three years after Ali had won the World Heavyweight Championship, he was publicly vilified for his refusal to be conscripted into the U.S. military, based on his religious beliefs and opposition to the Vietnam War. Ali stated, "I ain't got no quarrel with them Viet Cong... No Viet Cong ever called me nigger" – one of the more telling remarks of the era.

Widespread protests against the Vietnam War had not yet begun, but with that one phrase, Ali articulated the reason to oppose the war for a generation of young Americans, and his words served as a touchstone for the racial and antiwar upheavals that would rock the 1960s. Ali's example inspired Martin Luther King Jr. – who had been reluctant to alienate the Johnson Administration and its support of the civil rights agenda – to voice his own opposition to the war for the first time.

Malcolm X ( /ˈmælkəm ˈɛks/; May 19, 1925 – February 21, 1965), born Malcolm Little and also known as El-Hajj Malik El-Shabazz (Arabic: الحاجّ مالك الشباز‎), was an African-American Muslim minister and human rights activist. To his admirers, he was a courageous advocate for the rights of African Americans, a man who indicted white America in the harshest terms for its crimes against black Americans. Detractors accused him of preaching racism, black supremacy, antisemitism, and violence. He has been called one of the greatest and most influential African Americans in history.

Malcolm X's father died—killed by white supremacists, it was rumored—when he was young, and at least one of his uncles was lynched. When he was thirteen, his mother was placed in a mental hospital, and he was placed in a series of foster homes. In 1946, at age 20, he went to prison for breaking and entering.

In prison, Malcolm X became a member of the Nation of Islam and after his parole in 1952 he quickly rose to become one of its leaders. For a dozen years Malcolm X was the public face of the controversial group, but disillusionment with Nation of Islam head Elijah Muhammad led him to leave the Nation in March 1964. After a period of travel in Africa and the Middle East, he returned to the United States, where he founded Muslim Mosque, Inc. and the Organization of Afro-American Unity. In February 1965, less than a year after leaving the Nation of Islam, he was assassinated by three members of the group.

Maher Zain (Arabic: ماهر زين‎ ; born March 16, 1981 in Tripoli, Lebanon) is a Muslim Swedish R&B singer, songwriter and music producer of Lebanese origin. His debut album Thank You Allah, an internationally successful album with strong Muslim religious influences, was released in 2009. He released his follow-up album Forgive Me on April 2, 2012.

Maher Zain and his family moved to Sweden when he was eight years old. He completed his schooling there gaining a Bachelors degree in Aeronautical Engineering. After university he entered the music industry in Sweden and linked up with RedOne, the Moroccan-born Swedish producer.

When RedOne moved to New York in 2006 Maher Zain followed soon after to continue his music industry career in the USA producing for artists such as Kat DeLuna. On a visit home to Sweden he became engaged once more with his Islamic faith and decided to move away from a career as a music producer to become a singer/songwriter of contemporary R&B music with a strong Muslim religious influence.
