Muslim personal law refers to the legal framework governing personal matters for Muslims, including marriage, divorce, inheritance, and custody. It is derived from Islamic law, or Sharia, and is applied in various countries, often alongside secular laws. The specifics can vary based on local customs and interpretations of religious texts. In many countries, Muslim personal law allows for practices such as polygamy and provides guidelines for the distribution of property after death. It aims to address the unique needs of the Muslim community while balancing with the broader legal system in place.
