Salim went to primary school at Zenana Bible and Medical Mission Girls High School at Girgaum along with two of his sisters and later to St. Xavier's College, Bombay. Around the age of 13 he suffered from chronic headaches, making him drop out of class frequently. He was sent to Sind to stay with an uncle who had suggested that the dry air might help and on returning after such breaks in studies, he barely managed to pass the matriculation exam of the Bombay University in 1913.
