A seventh reported opinion says these children will be turned into dust on the Day of Resurrection. The wording ascribes this to some heterodox groups; it is not presented as the settled, universally accepted Sunni doctrine.
Two scholarly rules apply. First, reporting an opinion is not the same as endorsing it. Second, attribution and status within the discussion must be preserved.
Seen together, the seven positions differ in how they infer a child's state in the afterlife and what they treat as sufficient evidence. Reducing them to an undifferentiated “everyone agrees” would erase the very disagreement the passage documents.
