Abstract The monogamous and polygynous customary marriages of indigenous Black Africans have been fully legally recognised in South Africa since 1998. The outcome of a June 2022 apex Constitutional Court judgment will finally result in monogamous and polygynous Muslim marriages (nikāḥ) being fully legally recognized and regulated by the State by 2024. Since this recognition does not include the Islamic law of succession (which will not pass constitutional muster because of half-share to women), when Muslims die intestate, the secular law is expected to apply. The payment of mahr (dower) by the groom to the bride (an important ingredient of a nikāḥ contract) is therefore an important alternative tool for augmenting the inheritance of Muslim women during their lifetime. A novel fatwā issued by local Black African ulama in August 2022 brought to light several challenges faced by African Muslims regarding the relation of nikāḥ marriages to distinctive African traditional marriage practices like the lobolo (“bride price”) paid by the groom to the bride’s father. This paper examines the implications of mahr and lobolo on religious and customary marriages and the rights of local Black African Muslim women to inherit in terms of religion and custom.
