Sunni Islam ( /ˈsuːni/ or /ˈsʊni/) is the largest branch of Islam. Sunni Muslims are referred to in Arabic as ʾAhlu-s-Sunnati wa-l-Jamāʿah (Arabic: أهل السنة والجماعة‎), "people of the tradition of Muhammad and the consensus of the Ummah" or ʾAhlu-s-Sunnah (Arabic: أهل السنة‎) for short; in English, they are known as Sunni Muslims, Sunnis or Sunnites.

Sunni Islam is sometimes referred to as the orthodox version of the religion. The word "Sunni" comes from the term Sunnah (Arabic: سنة‎), which refers to the sayings and actions of Muhammad that are recorded in hadiths (collections of narrations regarding Muhammad).

The primary hadiths Al-Kutub Al-Sittah, in conjunction with the Quran, form the basis of all jurisprudence methodologies within Sunni Islam. Laws are derived from the text of the Quran and the hadith, in addition to using methods of juristic reasoning (like qiyas) and consensus (ijma). There is a multitude of scholarly opinions in each field; however, these can be summarised as either derived from the four major schools of thought (Madh'hab) or from an expert scholar who exercises independent derivation of Islamic Law (ijtihad). Both are considered valid as differences of opinion were present at the time of the early Muslims (the Salaf).

Zakir Abdul Karim Naik (Urdu: ذاکر عبدالکریم نائیک; born 18 October 1965) is an Indian public speaker on the subject of Islam and comparative religion. He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.

Zakir Abdul Karim Naik was born on 18 October 1965 in Mumbai, India. He attended St. Peter's High School in Mumbai. Later he enrolled at Kishinchand Chellaram College, before studying medicine at Topiwala National Medical College and Nair Hospital and later the University of Mumbai, where he obtained a Bachelor of Medicine and Surgery (MBBS). His wife, Farhat Naik, works for the women's section of the IRF.

Siraj Wahhaj (born Jeffrey Kearse, March 11, 1950) is an African-American convert to Islam. He is imam of Al-Taqwa mosque in Brooklyn, New York and the leader of The Muslim Alliance in North America (MANA).

Wahhaj was born as Jeffrey Kearse and raised in Brooklyn, New York. His mother Gloria Sage was a nurse and his father a hospital dietitian. His brother is writer and editor Gregory S. Kearse of Silver Spring, Maryland. He went to church religiously and went on to become a Sunday school teacher as a teenager in a Baptist church. Wahhaj then later went on to the New York University on a partial scholarship. He also played basketball where he met a teammate who interested him in the Nation of Islam, an African-American movement.

In 1969 he ended his schooling and joined the Nation of Islam, changing his name to Jeffrey12x. During this time he was vocal in his belief that “white people are devils." He said of this, “I preached it. I taught it.” Wahhaj says of his interest in the Nation: "It wasn't the theology that attracted me to the Nation of Islam at all... It was the kind of do-for-self black pride."

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.
