The charge of apostasy is often used by religious authorities to condemn and punish skeptics, dissidents, and minorities in their communities. From the earliest history of Islam, the crime of apostasy and execution for apostasy has driven major events in Islam. For example, the Ridda wars (civil wars of apostasy) shook the Muslim community in 632–633 AD, immediately after the death of Muhammad. These wars split the two major sects of Islam – Sunni and Shia, and caused numerous deaths. Sunni and Shia sects of Islam have long accused each other of apostasy.
