Abu Umamah reported: I heard the Messenger of Allah, peace and blessings be upon him, saying, “Recite the Quran, for on the Day of Resurrection it will come as an intercessor for its reciters. Recite the two illuminated chapters, Surah Al-Baqarah and Surah Ali Imran, for on the Day of Resurrection they will come as two clouds, or two shades, or two flocks of birds, pleading for those who recited them. Recite Surah Al-Baqarah for there is blessing in it, there is sorrow in ignoring it, and the magicians cannot confront it.”
