The merit of the beginning of Surah Al-Kahf

Q 7: Anyone who memorizes the first ten Ayahs (Qur'anic verses) of Surah Al-Kahf will be protected (Part No. 3; Page No. 139) from the trials of the Dajjal (the Antichrist). (Related by Muslim) Anyone who recites the last ten Ayahs of Surah Al-Kahf will be protected from the trials of the Dajjal. (Related by Al-Nasa'y) Another Hadith was reported by Al-Hakim which he ranked as Sahih (authentic) on the authority of Abu Sa`id that the Prophet (peace be upon him) said: Anyone who recites Surah Al-Kahf on Friday, there will be light for him between this Friday and the next one. What is the degree of authenticity of these Hadiths?

A: The well-known narration is "Anyone who memorizes the first ten Ayahs of Surah Al-Kahf." As for the other narration about the last ten Ayahs of Surah Al-Kahf, it is Shadh (a Hadith narrated by a trustworthy narrator, not in line with the narration of other trustworthy narrators in terms of wording, chain of narrators, or both).As for the Hadith of Abu Sa`id (may Allah be pleased with him), it is Hadith Hasan (a Hadith whose chain of narration contains a narrator with weak exactitude, but is free from eccentricity or blemish) and ranked as Sahih by Al-Hakim.
