In most Arabi and Islamic nationos there is a marriage contract, known traditionally as aqd qeran, aqd nekah or aqd zawaj, that long been established as an integral part of an Islamic marriage and is signed at the marriage ceremony. In Egypt, Syria, Palestine, Jordan and Lebanon, but not in other nations or regions, this contract is widely known as Katb el-Kitab. The contract is similar to the ketubah in Judaism, and outlines the rights and responsibilities of the groom and bride or other parties involved in the marriage proceedings.
