In medieval Islamic societies, the qadi (Islamic judges) usually could not interfere in the matters of non-Muslims unless the parties voluntarily choose to be judged according to Islamic law, thus the dhimmi communities living in Islamic states usually had their own laws independent from the Sharia law, such as the Jews who would have their own Halakha courts.[5] Islamic empires allowed non-believers to have their own laws and courts in exchange for a Jizya poll tax.
