In the Name of Allaah, the Most Merciful, the All-Merciful.

Know that the Nullifiers of Islaam are ten.

First: Shirk (associating partners) in the worship of Allaah. Allaah says: “Verily, Allaah does not forgive that partners be associated with Him in worship (i.e. Shirk), but He forgives what is less than that to whom He wills.” *Surah An-Nisaa: 116] And He says: “Verily, the one who mixes partners in worship with Allaah (Shirk), then Paradise has been made forbidden for him and his final abode will be the Hellfire. And the wrongdoers will not have any helpers (in Hell).” *Surah Al-Maa’idah: 72+ What falls into this is performing sacrifices to someone other than Allaah,
such as the person who offers a sacrifice to the Jinn or to a grave.

Second: Whoever places intermediaries between himself and Allaah, calling unto them and asking intercession from them, and seeking reliance in them, has committed disbelief according to the unanimous agreement (Ijmaa’).

Third: Whoever does not hold the polytheists to be disbelievers, or has doubts about their disbelief or considers their ways and beliefs to be correct, has committed disbelief.

Fourth: Whoever believes that some guidance other than that of the Prophet’s ﷺ is more complete than his guidance and that someone else’s judgement is better than his judgement, such as the one who prefers the judgement of the Tawaagheet (pl. of Taaghoot; false deities/religions) over his judgement, then he is a disbeliever.
Fifth: Whoever hates something that the Messenger came with, even though he may act on it, has disbelieved.

Fifth: Whoever hates something that the Messenger came with, even though he may act on it, has disbelieved.

Sixth: Whoever mocks or ridicules any part of the Messenger’s Religion or its rewards or punishments has committed an act of disbelief. The proof for this is Allaah’s statement:

“Say: ‘Was it Allaah and His verses and His Messenger that you were mocking? Make no excuses, you have disbelieved after having had faith.”  
[Surah At-Tawbah: 65-66]

Seventh: Sorcery, which includes magic spells that cause a person to hate something he seeks after (sarf) or love something he doesn’t seek after (‘atf). So whoever performs it or is pleased with it being done, has committed disbelief. The proof for this is Allaah’s statement:

“And neither of these two (angels) would teach anyone until they had first said to them: ‘We are only a trial (for the people), so do not commit disbelief.’”  
[Surah Al-Baqarah: 102]

Eighth: Supporting and assisting the polytheists against the Muslims. The proof for this is Allaah’s statement:

“And whoever amongst you takes them (i.e. the disbelievers) as allies and protectors then he is indeed from among them. Verily, Allaah does not guide a wrong-doing people.” 
[Surah Al- Maa’idah: 51]

Ninth: Whoever believes that it is permitted for some people to be free of (implementing) the Sharee’ah (revealed laws) of Muhammad (i.e. Islaam), just as it was permitted for Al-Khidr to be free from the Sharee’ah of Moosaa, then he is a disbeliever.

Tenth: Turning away from Allaah’s Religion, not learning it or implementing it
(is an act of disbelief). The proof for this is Allaah’s saying:

“And who does more wrong than he who is reminded of the ayaat (signs/verses) of his Lord, then turns away from them. Verily, We shall extract retribution from the criminals.” 
[Surah As-Sajdah: 22]

There is no difference, with regard to (committing any of) these nullifiers, between the one who jokes, the one who is serious or the one who does so out of fear. The one who commits them due to being coerced (is excused). All of these (ten) matters are from the gravest in danger and from those that most often occur. So the Muslim must beware of them and fear from these acts befalling him. We seek refuge in Allaah from those things that bring about His Anger and painful Punishment. May the peace and blessing be on the best of His creatures, Muhammad ﷺ.
