This study is an attempt to scrutinise the narrations that have an impact on authenticity, which al-Tabari mentioned in his interpretation of the story of the Companions of the Cave. The study examined these narrations in terms of the isnad mentioned by al-Tabari, their agreement with the context of the verses, and the extent of anomalies in their text. Several research methods were employed for this purpose, including inductive and critical approaches. The study used the weighting rules, the most important of which are: considering the acceptance of the attribution, examining the possibility of combining statements, and considering the extent to which the statement agrees with the context of the verses. The study concludes that the context plays the most important role in arriving at the closest meaning of those sayings
