Did Baha’u’llah say that the Afterlife is beyond description, meaning we cannot know what it is like? Therefore the Quranic descriptions of the Afterlife must be parables of something we can’t understand?
Baha’u’llah described the conditions, including the stench, of the Siyah Chal (“Black Pit”) as being “beyond description”. This does not mean that we cannot imagine it, nor the Siyah Chal was a metaphor or parable of some personal suffering of His that we cannot comprehend. Baha’u’llah affirms the Quranic descriptions of the After life in His Tablet to Varqa.
