1. To associate others with Allah in worship. The Qur'an says: "Allah forgives not (the sin of) setting up partners with Him in worship, but He forgives whom He pleases other sins than this." (Soorah 4: 1 16)

"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." (Soorah 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.

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

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

5 . Those who hate anything that the Prophet came with are also disbelievers even if they act upon them. The Qur'an says: "That is because they hate that which Allah sent down, so He has made their deeds fruitless." (Soorah 47:9)

6. Those who ridicule anything that Islam came with, such as punishment and reward in the Hereafter, are disbelievers. The Qur'an says: "Say: 'Was it at 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 turning someone away from somebody that he or she loves, and making someone love someone or something he or she does not normally like. Whoever practices magic or approves of it is a disbeliever, as evidenced by the Qur'anic 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)." (Soorah2:102)

8. To take the disbelievers for friends, give them support and assistance against the Muslims is an act of disbelief. The Qur'an says: "And he amongst you that turns to them (for friendship) is of them. Verily Allah guides not a people unjust." (Soorah 5:51)

9. Those who believe that it is in their power or authority to forsake the law of Islam are disbelievers. The Qur'an 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." (Soorah 3:85)

10. To turn away from Islam and to stubbornly refuse to learn its teachings or act upon them. The Qur'an 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 We shall exact (due) retribution." (Soorah 32:22)

In all of these invalidators, there is no difference between one who does them jokingly, seriously, or in fear, except for one who is compelled against his will. All of these matters are most dangerous and most of them are occurring (amongst the Muslims). Therefore, it is necessary for the Muslim to beware of them and fear for himself concerning them.

The fourth point mentioned above also includes those who believe that man-made laws are better than the Islamic Law, that the Islamic Law is not suitable to be implemented in the present century, that Islam is the reason behind Muslims' backwardness in some spheres of life, or that it is not applicable in other spheres of life apart from regulating one' s life with one's Lord. This point also includes those who believe that cutting off the thief's hand is a backward law that should not be implemented in the present-day society. It also includes those who believe that it is permissible to dispense with the Islamic Law in matters relating to the social life and the boundary limits for the lawful and the unlawful even if they do not believe that other laws are not better than the Islamic Law. For this means that they have made lawful what Allah had already made unlawful. Whoever makes lawful what Allah has declared unlawful, things that are known in religion by necessity such as adultery, drinking alcohol, usury and ruling with other than Allah's Law, is a disbeliever with the unanimous agreement of all Muslim scholars.

We seek Allah's refuge from His painful chastisement as well as from those things that cause His wrath. Allah's Peace and Blessing be upon His Messenger, his pure family and noble Companions.
