Judaism (from the Latin Iudaismus, derived from the Greek Ioudaïsmos, and ultimately from the Hebrew יהודה, Yehudah, "Judah"; in Hebrew: יַהֲדוּת, Yahadut, the distinctive characteristics of the Judean ethnos) is a monotheistic religion originating in the Hebrew Bible (also known as the Tanakh) and explored in later texts such as the Talmud. It has been defined ethnically as "the religion, philosophy, and way of life of the Jews" and religiously as "a covenant between God and the Jewish people that can be traced back to the prophets Abraham and Moses".Rabbinic Judaism holds that God revealed his laws and commandments to Moses on Mount Sinai in the form of both the Written and Oral Torah. This assertion was historically challenged by the Karaites, a movement that flourished in the medieval period, which retains several thousand followers today and maintains that only the Written Torah was revealed. In modern times, liberal movements such as Humanistic Judaism may be nontheistic.

Judaism claims a historical continuity spanning more than 3,000 years. It is one of the oldest monotheistic religions, and the oldest to survive into the present day. The Hebrews / Israelites were already referred to as "Jews" in later books of the Tanakh such as the Book of Esther, with the term Jews replacing the title "Children of Israel". Judaism's texts, traditions and values strongly influenced later Abrahamic religions, including Christianity, Islam and the Baha'i Faith. Many aspects of Judaism have also directly or indirectly influenced secular Western ethics and civil law.

Ahmed Hoosen Deedat (Arabic: احمد حسين ديدات; 1 July 1918 – 8 August 2005) was a South African writer and public speaker of Indian descent. He was best known as a Muslim missionary who held numerous inter-religious public debates with evangelical Christians, as well as video lectures, most of which centred around Islam, Christianity and the Bible. He also established the IPCI, an international Islamic missionary organisation, and wrote several booklets on Islam and Christianity which were widely distributed by the organisation. He was awarded the prestigious King Faisal International Prize in 1986 for his 50 years of missionary work. One focus of his work was providing Muslims with theological tools for defending themselves against active proselytising by Christian missionaries.^{[citation needed]} He used English to get his message across to Muslims and non-Muslims in the western world.

Ahmed Deedat was born in the town of Tadkeshwar, Surat, Bombay Presidency, British India in 1918. His father had emigrated to South Africa shortly after the birth of Ahmed Deedat. At the age of 9, Deedat left India to join his father in what is now known as Kwazulu-Natal. His mother died only a few months after his departure. Arriving in South Africa, Deedat applied himself with diligence to his studies, overcoming the language barrier and excelling in school, even getting promoted until he completed standard 6. However, due to financial circumstances, he had to quit school and start working by the time he was the age of 16.

Oprah Winfrey (born Orpah Gail Winfrey; January 29, 1954) is an American media proprietor, talk show host, actress, producer, and philanthropist. Winfrey is best known for her self-titled, multi-award-winning talk show, which has become the highest-rated program of its kind in history and was nationally syndicated from 1986 to 2011. She has been ranked the richest African-American of the 20th century, the greatest black philanthropist in American history, and was for a time the world's only black billionaire. She is also, according to some assessments, the most influential woman in the world.

Winfrey was born into poverty in rural Mississippi to a teenage single mother and later raised in an inner-city Milwaukee neighborhood. She experienced considerable hardship during her childhood, claiming to be raped at age nine and becoming pregnant at 14; her son died in infancy. Sent to live with the man she calls her father, a barber in Tennessee, Winfrey landed a job in radio while still in high school and began co-anchoring the local evening news at the age of 19. Her emotional ad-lib delivery eventually got her transferred to the daytime-talk-show arena, and after boosting a third-rated local Chicago talk show to first place, she launched her own production company and became internationally syndicated.
