The Qur'an often recounts earlier prophets' experiences concisely. Later exegetes transmitted extensive expansions, many drawn from historical narratives circulating among earlier scriptural communities. The popularity of such a story does not establish every detail as Qur'anic fact or authentic hadith.
A detail explicitly established in the Qur'an or sound prophetic teaching has a different status from an unverified report about names, dates, places or dialogue. Unsupported specificity should not be asserted with certainty.
The Qur'anic narrative principally aims at guidance, faith, ethical insight and admonition. Long speculative embellishments may obscure that purpose.
