What are the things that take a person out of the religion, take him from being a Muslim to being an infidel?

 Nullifiers of Islam

 

Islam has contradictions, which a Muslim must beware of. Scholars have mentioned them in the chapter on ruling on an apostate. They said: He is a Muslim who disbelieves after his conversion to Islam. They mentioned many things that nullify Islam, such as: calling on the dead and seeking help from the dead, such as cursing the religion, cursing the Messenger, may God bless him and grant him peace, and cursing the Qur’an. Mocking the Qur’an, mocking religion, abandoning prayer, denying its obligation, denying the obligation of zakat, denying the obligation of fasting Ramadan, denying the obligation of Hajj if one is able, if he denies the obligation of that; Disbelief, also if adultery is permissible; It is blasphemy, if sodomy is permissible. It is blasphemy, if he says: Wine is permissible. He is disbeliever if he says: usury is permissible; Infidelity, and so on, there are many things they mentioned that they called: nullifiers of Islam, meaning: that lead to apostasy - we ask God for well-being. 
The Muslim reality is in a dangerous state, especially in this era...?
It is a dangerous era, especially in many countries that are not governed by Sharia law. The preachers of falsehood are many, and the contradictions of Islam are widespread. There is no power nor strength except in God.
