Q 5: What
is the ruling on declaring specific persons disbelievers?
A:
Anyone who does, says, or believes in some acts that are akin to Kufr (disbelief) is considered Kafir i.e. disbeliever, and is treated accordingly whether he is particularized or not, as the evidence is general in this regard. For example, a person who supplicates to or slaughters for other than Allah, or utters words of disbelief such as abusing Allah, His Prophet, or mocking an Islamic tenet is a Kafir, He must be asked to perform Tawbah (repentance to Allah), otherwise it is obligatory for the Muslim rulers to apply capital punishment for Riddah (apostasy).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
