Defining the Nullifiers of Islam

The questioner Ibrahim from Riyadh asks: Are the nullifiers of Islam limited to a specific number, and what are they?
Answer: The nullifiers of Islam are numerous and not limited to a specific count; because one person may count them while another does not, depending on the opinions of scholars, their independent legal reasoning, and their derivation of rulings from the evidence of the Shari'ah. For example, one person may count four hundred nullifiers, while another counts five hundred, because he derived them from other evidence. Thus, this is subject to the evidence of the Shari'ah; the nullifiers of Islam are subject to the evidence of the Shari'ah.
The scholars have mentioned them in the chapter on the ruling of the apostate. Whoever wants to find them will find them in the chapter on the ruling of the apostate. One should refer to this great chapter and pay attention to it so that he may know from it the nullifiers of Islam, such as associating partners with Allah, worshipping idols and graves other than Allah, calling for aid from them, and making vows to them. All of this is apostasy from Islam; all of this is among the nullifiers of Islam. Likewise, insulting the religion is among the nullifiers of Islam; insulting the Messenger of Allah (peace and blessings be upon him) is among the nullifiers of Islam; insulting Allah is among the nullifiers of Islam; belittling Islam is among the nullifiers of Islam. Saying that zina is not forbidden is among the nullifiers of Islam. If he says that riba is not forbidden, it is among the nullifiers of Islam. If he says that oppressing people is not forbidden, this is among the nullifiers of Islam. If he says that prayer is not obligatory, this is among the nullifiers of Islam. If he says that zakah is not obligatory, it is among the nullifiers of Islam. If he says that fasting Ramadan is not obligatory, this is among the nullifiers of Islam. If he says that Hajj is not obligatory with the ability to perform it, this is among the nullifiers of Islam. If he says that backbiting is lawful and talebearing is lawful, this is among the nullifiers of Islam. Thus, it has many categories. But whoever wants to know them in truth, he must refer to the chapter on the ruling of the apostate. He must study this chapter in all four schools of jurisprudence: the Hanafi, the Maliki, the Shafi'i, the Hanbali, and others. He must study this chapter, reflect, and examine the evidence of the Shari'ah so that he may know the nullifiers. Yes.
