Finding the reason for the excommunication of Muslims in the interpretation of the Holy Quran

The excommunication of Muslims is in clear contradiction of the verses of the Holy Qur'an, the lifestyle of the Holy Prophet (PBUH) and the Companions and the theories of Islamic scholars, and it has no rational or religious evidence. The first and lowest degree of becoming Muslim is proved by saying two testimonies: ‘I bear witness that there is no god but Allah, And I bear witness that Muhammad is the messenger of Allah’. The Holy Qur'an protects the life of these people and forbids them from excommunicating themselves as Muslims. It also forbids putting pseudo efforts in the name of jihad [in the way of God] inviting infidels to Islam, and prohibits unhealthy intentions such as waging war for collecting booty and the acquiring unsustainable worldly possessions. The Quran invites human beings to everlasting values. There have been several impure motives behind excommunications including: psychological disorder, satanic temptations and looking for worldly pleasures. The Holy Qur'an considers inclination towards the world as the main cause of Muslim excommunication. Promising Paradise, Houri [a beautiful young woman, especially one of the virgin companions of the faithful in the Muslim Paradise], distortion of Qur'anic verses and misinterpretation of them, can also be other factors having complementary functions that make the enemies of Islam strong enough to do away with this final religion of mercy and peace.
