Do the nullifiers of Islam apply to groups as they apply to individuals, and do they apply to the Muslim ruler who governs by the law of Allah, thus invalidating his Islam?

Dealing with the nullifiers of Islam is serious, due to the grave consequences that entail. It is not permissible to declare a specific person an apostate merely because they belong to a group to which nullifiers of faith are attributed. Rather, it is first necessary to establish the authenticity of this attribution to the person, then their acknowledgment of this nullifier, whether in belief or action, and then to verify the fulfillment of the conditions for declaring someone a disbeliever and the absence of any impediments.

Conditions for declaring someone a disbeliever: 1. Proof that the act is disbelief (kufr). 2. The description applies to the person, meaning they are aware of it and intend it. Otherwise, they are not to be declared a disbeliever until proof is established against them.

Beware of rushing into declaring someone a disbeliever, as it has dangerous implications, such as condemning the person to Hellfire, hating them, and disavowing them. There is no difference between the ruler and the ruled regarding the consideration of nullifiers and their effect.

Judging groups and sects to be disbelievers falls under the category of declaring the type (genus) to be disbelievers, not the individual (ayn), whereas declaring a specific person among them to be a disbeliever requires the fulfillment of the conditions and the absence of any impediments.
