The Messenger of Allah ﷺ said, "Recite the two luminous surahs, recite al-Baqarah and Aal Imran, for they will come on the Day of Resurrection like two clouds, or two flocks of birds spreading their wings in rows."
قال رسول الله ﷺ: اقرؤوا الزهراوين، اقرؤوا البقرة وآل عمران، فإنهما تأتيان يوم القيامة كأنهما غمامتان، أو فرقان من طير صواف.
Bazzar narrated it in Kashf Astar (2303), from Ahmad bin Mansur, who said, Abdullah bin Salih Abu Salih narrated to us, Layth informed us, from Saeed, from Abu Hurairah, and he mentioned it.Its chain is hasan because of Abdullah bin Salih, the scribe of Layth, for there is disagreement about him, though his hadith is hasan when supported by corroborating narrations.
