Recurrence does not require every detail of an event to be reproduced identically each time. The same account or reminder may return in concise narrative, fuller explanation, dialogue, or warning. A changed presentation highlights a different dimension of meaning.
Accounts of earlier prophets appear from varied angles in al-Aʿrāf, Hūd, al-Shuʿarāʾ, al-Ṣāffāt, and al-Dhāriyāt. Their function is not to replicate a complete historical register in every surah, but to reinforce the relevant lesson or argument.
Interpretive benefit: identify the shared material while also recognizing the new point emphasized in each context.
