"At Qum are deposited the remains of his [ Imam Rida's] sister, Fatimiy-i-Ma'sumih, i.e. the Immaculate, who, according to one account, lived and died here, having fled from Baghdad to escape the persecution of the Khalifs; according to another, sickened and died at Qum, on her way to see her brother at Tus. He, for his part, is believed by the pious Shi'ahs to return the compliment by paying her a visit every Friday from his shrine at Mashhad." Lord Curzon's "Persia and the Persian Question," vol. 2, p. 8.)
