How authentic is the following Hadith: The Prophet (peace be upon him) said concerning Surahs (Qur'anic chapters)
Banu Israel (Al-Isra'),
Al-Kahf, Ta-Ha, Maryam and Al-Anbiya':
They are among the first revealed Surahs and the first which I memorized from the Qur'an.
The Hadith referred to is narrated by Imam
Al-Bukhari and is attributed to
Ibn Mas`ud (may Allah be pleased with him) as a Hadith Mawquf (words or deeds narrated from a Companion of the Prophet that are not attributed to the Prophet). He (Ibn Mas`ud) said regarding Surahs of
Banu Israel, Al-Kahf and Maryam:
They (Part No. 3; Page No. 129) are among the first revealed Surahs and the first which I memorized from the Qur'an.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
