The Islamic Sharia Council (ISC) is a British organisation that provides Islamic legal rulings and advice to Muslims in accordance with its interpretation of Islamic Sharia based on the four Sunni schools of thought. It has no legal authority and its rulings are considered unofficial. It primarily handles cases of marriage and divorce and, to a lesser extent, business and finance. Thousands of Muslims have turned to the Council to resolve family and financial issues. The Economist magazine states it has offered rulings to "thousands of troubled families since the 1980s", the council states that it has dealt with an average of between 200 and 300 cases monthly as of January 2012.
