Are Aminah bint Wahb, Abd al-Muttalib, and Abu Talib in Hellfire because they died not upon Tawhid?

Abu Talib, the Prophet's uncle, is among the inhabitants of Hellfire due to his death in disbelief. The same applies to Aminah, the Prophet's mother, based on the hadith (definition): "I asked my Lord for permission to seek forgiveness for my mother, but He did not permit me," and His saying: "Your mother is in the Hellfire," and the hadith: "Indeed, my father and your father are in the Hellfire." As for Abd al-Muttalib, a hadith was narrated concerning him: "If you had reached them, you would not have seen Paradise until your great-grandfather sees it," but this is a weak hadith. Some scholars are of the view that he is among the people of the fatrah (interval), to whom the call of Islam did not reach.
