Is what is stated in the book "Fiqh as-Sunnah" by Sayyid Sabiq—that the verse, "The old man and the old woman, if they commit adultery, stone them absolutely, as a recompense for the pleasure they have enjoyed," was among what Allah revealed from the Qur'an; and that Surah Al-Ahzab was equal in length to Surah Al-Baqarah; and that Ibn Mas'ud forgot the two "Mu'awwidhatayn"—correct? And what is the opinion regarding Sayyid Sabiq?

The Hadith of the 'Ajma' (animal) was authenticated by Al-Hakim, and Al-Dhahabi agreed with him. It was narrated by Al-Tabarani. The Hadith of Ubayy was authenticated by Ibn Hibban, Al-Hakim, and Al-Dhahabi. As for what was narrated from Ibn Mas'ud regarding the Mu'awwidhatayn (chapters of refuge), it was authenticated by Al-Suyuti and Ibn Hajar, but none of the Companions followed him on it. What supports their being part of the Qur'an is the consensus of the scribes of the Qur'anic manuscripts during the time of Abu Bakr and Uthman, and the Prophet, peace and blessings be upon him, reciting them in the Fajr prayer. Al-Nawawi, Ibn Hazm, and Al-Fakhr Al-Razi denied what was narrated from Ibn Mas'ud concerning them. What supports his (Ibn Mas'ud's) not denying their Qur'anic nature is that the recitation of Asim, Hamza, and Al-Kisa'i traces its chain of transmission back to him, and these two surahs are among what they recited. Ibn Kathir mentioned that Ibn Mas'ud perhaps did not receive it through widespread transmission (tawatur), and then perhaps he retracted his opinion and adopted the view of the majority.
