The meaning of the Prophet's (peace and blessings be upon him) saying: "They are all in the Fire"

Question:
Honorable Shaykh, and in the rest of his question he asks: Is the Prophet's (peace and blessings be upon him) saying that "they are all in the Fire" evidence that these sects are disbelievers, or is it a warning?

Answer:
"They are all in the Fire," as the Prophet (peace and blessings be upon him) said, for he does not speak from desire. However, some of them are in the Fire because of their disbelief and will remain in it forever, while others enter the Fire because of a major sin and their disobedience, but they will not remain in it forever, provided their disobedience does not take them out of the religion and their separation does not take them out of the religion. They may be excused in the Fire, but they will not remain in it forever. This distinction is necessary: they are in the Fire either because they are arrogant or because they are the perpetrators of a major sin. Yes.
