The document discusses the history of divisions within Islam after the death of the Prophet Muhammad. It identifies three main groups: 1) The chosen followers who closely followed the teachings and example of the Prophet, including Ali and the Prophet's household. 2) Those who went astray by prioritizing worldly gains and changing the Prophet's teachings and traditions. 3) Hypocrites who did not truly believe. The document argues the divisions are due to some people following the Prophet closely and others going their own way after him.
