Is it permissible to rule that a specific person is among the people of the Fire?

Question:
This is a question about ruling that a specific person is among the people of the Fire.

Answer:
No, we do not rule that a specific person is among the people of the Fire, except for those whom Allah or the Messenger (peace and blessings be upon him) has ruled upon. As for one whose name or ruling has not been mentioned by the Messenger or in the Qur'an as being among the people of the Fire, we do not rule on him, because we do not know what his final state will be. He may be concluded with Islam, or he may be concluded with repentance, in which case he will be among the people of Paradise. But we say: whoever does such-and-such is a disbeliever; whoever does one of the nullifiers of Islam is a disbeliever. And we do not say that he is among the people of the Fire, but we say that if he dies upon it, if he dies upon disbelief, then he is among the people of the Fire, with this condition.
If he dies upon disbelief, or upon this nullifier of the nullifiers of Islam, then he is among the people of the Fire. The condition is necessary. We do not say he is among the people of the Fire absolutely, because we do not know how he will be concluded.
