Ok. So, what you are saying is that because Ibn Kathir did not understand the allegory of 74:31 means he is correct? GOD is stating the very same verse that it is an allegory meaning the obvious meaning is NOT what it means. It is in the same verse.
Basically, you are saying you trust fabricated hearsay over clear the Quran. The verse is clear. Only those with doubts and the disbelievers do not understand the allegory of 74:31. Consequently, take the literal meaning…just like GOD says they will do. Your lack of belief in GOD’s revelations is apparent.
