Deedat was born in the town of Tadkeshwar, Surat, Bombay Presidency, British India in 1918. His father had emigrated to South Africa shortly after his birth. 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 at the age of 16.
