Amina hailed from a family of activists. Her father, Ebrahim Asvat was a companion of Gandhi during his stay in South Africa and was chairman of the Transvaal British Indian Association, which later became the Transvaal Indian Congress.
She met her husband Yusuf when he was interviewing candidates for bursaries offered by India. Although she failed to get a passport to study in India, she married Yusuf and also became a strong leader in women's movements in South Africa, despite repeated banning orders which confined her to her home. Yusuf Cachalia died in 1995 in New Delhi.
