How sound is the Hadith attributed to Ibn Abbas regarding the exegesis of the Almighty’s saying, “And when the stars lose their luster” (Qur’an 81:2), the text of which is: “On that day, no star will remain in the sky but will fall to the earth, to the extent that the inhabitants of the seventh earth will be terrified by what the upper one has met and befallen”?

The statement attributed to Abdullah ibn Abbas, may Allah be pleased with him, regarding the interpretation of Allah's saying: (And when the stars lose their luster) [At-Takwir/2], has not been transmitted with a sound chain of narration. Rather, it came through two mursal (indirect) routes (Abu Salih from Ibn Abbas, and Ad-Dahhak ibn Muzahim from Ibn Abbas), both of which are not authentic.

Indeed, two interpretations of this verse have been narrated from Ibn Abbas: The first: through Ali ibn Abi Talhah from Ibn Abbas, stating "they changed." This chain has a discontinuity, but some scholars rely on it. The second: through Muhammad ibn Marwan from Al-Kalbi from Abu Salih from Ibn Abbas, stating "they fell upon the face of the earth." This chain is very weak, and Muhammad ibn Marwan and Al-Kalbi are liars.

As for interpreting the verse to mean: "they fell," this is the opinion of many exegetes such as Mujahid and Qatadah. However, this does not indicate the authenticity of the aforementioned narration from Ibn Abbas in its entirety and details, because the interpretation of a word differs from the details of unseen matters that require a firm report.
