The Messenger of Allah ﷺ said, "I have been given the closing verses of Surah al-Baqarah from a treasure house beneath the Throne, which were not given to any prophet before me."
قال رسول الله ﷺ: أعطيت خواتيم سورة البقرة من بيت كنز من تحت العرش، لم يعطهن نبي قبلي.
Ibn Mardawayh narrated it via Sufyan Thawri, from Mansur, from Rabi bin Harash, from Zayd bin Dhubyan, from Abu Dharr, and he related it. Ibn Kathir cited it in his Tafsir (1/506). Zayd bin Dhubyan is described as "maqbul" as stated in Taqrib, and this is indeed the case because he has corroboration. This is because Imam Ahmad also narrated it (21345) via Shayban, from Mansur, from Kharasha bin Hurr, or Marur bin Suwayd, from Abu Dharr, and he related it. Kharasha bin Hurr and Marur bin Suwayd are both reliable narrators. In some narrations "and" appears instead of "or," and in another, it reads, "from Kharasha bin Hurr, from Marur bin Suwayd," which is a scribal error.It causes no harm that Jareer narrated it from Mansur with his chain, from someone who related it to him from Abu Dharr, and Imam Ahmad narrated it through him as well (21343), for whoever names his source is evidence against whoever does not.Hakim narrated it (1/562) through another route, from Abdullah bin Salih the Egyptian, who said, "Muawiya bin Salih informed me, from Abu Zahiriya, from Jubayr bin Nufayr, from Abu Dharr, that the Messenger of Allah ﷺ said, 'Allah sealed Surah Baqarah with two verses that He gave me from His treasure beneath the Throne, so learn them and teach them to your women and your children, for they are prayer, and Quran, and supplication.'"Hakim said, "This is a sahih hadith according to the standard of Bukhari." Dhahabi challenged this, saying, "Bukhari did not rely on Muawiya as evidence." The chain also includes Abdullah bin Salih the Egyptian, the scribe of Layth, concerning whom there is disagreement, though his hadith is hasan when it comes to corroborating narrations and supporting evidence, as is the case here.It was also reported from Ibn Masud as a stopped narration attributed to him alone.
