This study concludes that the background of the emergence of the MUI fatwa on life insurance is due to public question about life insurance, whether the legal status or its  activity are in accordance with the Shari'ah. The legal basis used by MUI in establishing fatwa on life insurance is the Qur'an, al-hadith and fiqh muamalah. MUI fatwa used istinbat method to regulate the life insurance viewed from the concept of maslahah is called maslahah the mu'tabarah (acceptable).
