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.
Ahmad (21345) narrated it from Husayn, who said, Shayban narrated to us from Mansur, from Rubai, from Kharasha bin Hurr, from Marur bin Suwayd, from Abu Dharr, and he mentioned it. Its isnad is hasan. See its takhrij in the Book of Iman.
