 As a boy , Jinnah lived for a time in Bombay with an aunt and may have attended the <unk> Das Tej Primary School there , later on studying at the Cathedral and John Connon School . In Karachi , he attended the Sindh @-@ Madrasa @-@ <unk> @-@ Islam and the Christian Missionary Society High School . He gained his matriculation from Bombay University at the high school . In his later years and especially after his death , a large number of stories about the boyhood of Pakistan 's founder were circulated : that he spent all his spare time at the police court , listening to the proceedings , and that he studied his books by the glow of street lights for lack of other illumination . His official biographer , Hector Bolitho , writing in 1954 , interviewed surviving boyhood associates , and obtained a tale that the young Jinnah discouraged other children from playing marbles in the dust , urging them to rise up , keep their hands and clothes clean , and play cricket instead .
