Mandela is referring to Sayed Abdurahman Moturu, the Prince of Madura, rather than Sheikh Abdurahman Matebe. Moturu and Matebe were two of three leaders of resistance to the Dutch banished to the Cape in the mid-1740s. Moturu, one of Cape Town's first imams, was exiled to Robben Island and died there in 1754. In 1969 the Moturu Kramat, now a sacred site for Muslim pilgrimage on Robben Island, was built to commemorate him. Muslim political prisoners would pay homage at the shrine before leaving the island.
