Or are you trying to solve a legal problem between two Muslims in the US? Arbiration offers Muslims who are involved in legal disputes the possibility of settling their problems Islamically. Arbitration works within the US legal system through the arbitration route. (The arbitration route is a well developed system also used by non-Muslims because it is usually much cheaper and much faster). The judges refer the case to binding arbitration (both parties agree in writing before the arbitration to abide by the ruling of the arbitration panel). The panel decides the case Islamically and the case is referred back to the US court system and the referring judges for execution of the agreement. Legally valid in the USA. However, both Muslims need to agree on a mutually acceptable Islamic arbitrator. The arbitrating Muslim individual should be well versed in Islamic Law as well as have meet the needs of the American court.
