Rabie was born in
Middelburg in the former
Transvaal in August 1938. His father was
Indian and his mother was a
Coloured domestic worker. The government evicted the family from their farm when Rabie was a child and they moved to
Pretoria, where Rabie matriculated in 1958 at Pretoria Indian Boys' School. He trained as a teacher in
Coronationville and took up his first teaching post in
Potchefstroom in 1966. He left teaching after two years due to disputes with the teaching authorities, and by then he was active in the Federal Coloured People's Party (FCPP), having become an organiser for the party in the Transvaal in 1967. In 1969, the party nominated him to sit on the
Coloured Representative Council as the representative of the
Reiger Park constituency in
Boksburg, Transvaal. After launching an unsuccessful bid to become leader of the FCPP in 1975, Rabie fell out with the new party leadership, among other things over his support for political proposals which would see independent
Coloured homelands established in each of
South Africa's provinces. He was expelled from the party and sat in the CRC as an independent for three-and-a-half years, becoming the unofficial leader of the independents' caucus in the council. He joined the
Labour Party in 1978 and continued to serve on the CRC until it was disbanded in 1980. == Parliament ==
