Invalidators of islam

Allah has made it obligatory upon all His slaves to enter Islam and hold onto it and warned them against following other than Islam. He also sent His Prophet Muhammad peace be upon him, to call all mankind to it. Allah has informed us in the Quran that guided are those who follow the teachings of Islam, and misguided are those who reject them. He warned in many Verses against the causes of apostasy and all forms of Shirk and disbelief. Religious scholars have mentioned that there are a number of invalidating factors that are bound to take one out of the fold of Islam

Ten most critical invalidators of Islam

1. To associate others with Allah in worship. The Quran says:
"Allah forgives not (the sin of) setting up partners with Him in worship, but He forgives whom He pleases other sins than this" [4:116]

"whoever sets up partners with Allah in worship, Allah will forbid him Paradise, and the Fire will be his abode. For the wrongdoers there are no helpers" [5.72]

Forms of worship include calling upon the dead, seeking their assistance, offering sacrifices to them, and taking vows in their names.

2. To set up intermediaries between oneself and Allah, seeking their intercession and putting absolute trust in them. Those who do so are unanimously considered disbelievers.Such as going to shrines - or asking someone to pray because he/she is perceived as being more spiritual or closer to Allah.

3. Not to accuse polytheists and those who commit Shirk or disbelief, to doubt as to their being disbelievers, or to approve of their beliefs.

4. to believe that the Prophets guidance is not complete or perfect or that other people's ruling and judgement is better than his. Those who prefer the rule of false gods are blatant disbelievers.

5.those who hate anything that the Prophet pbuh came with are also disbelievers even if they act upon them. The Quran says
" that is because they hate that which Allah sent down, so He has made their deeds fruitless."

6. Those who ridicule anything that Islam preaches, such as punishment and reward in the Hereafter, are disbelievers. The Quran says:
"say: was is it Allah , and His Signs, and His Messenger, that you were mocking? Make no excuse you have rejected faith after you had accepted it" [9:65,66]

7. Magic in all its forms including turnings someone away from somebody that he she loves and making somebody love someone or something he or she does not normally like. Whoever practices magic or approves of it is is a disbeliever, as evidenced by the Quranic Verse that says:
"But neither of these [two angels] taught anyone [such things] without saying 'we are only for trial, so disbelieve not [by learning this magic from us] [2:102}

8. to take the disbelievers for friends, give them support and assistance against the Muslims is an act of disbelief. The Quran says:
"And one amongst you that turns to them [for friendship] is of them.Verily Allah guides not people unjust."

9. those who believe that it is in their power or authority to forsake the law of Islam are not disbelievers. The Quran says:
"And whoever seeks a religion other than Islam, it will never be accepted of him; and in the Hereafter he will be one of the losers."[3:85]

10. To turn away from Islam and to stubbornly refuse to earn its teachings or act upon them. The Quran says:
"And who does more wrong than he who is reminded of the Signs of His Lord, Then he turns away there from? Verily from those who transgress W shall exact [due] retribution"
