Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) said: "Learn the two radiant ones, al-Baqarah and Al Imran, for they will come on the Day of Resurrection as though they were two clouds, or two canopies, or two flocks of birds in ranks, pleading on behalf of their companion. Learn Surah al-Baqarah, for taking it up is a blessing and abandoning it is a cause of regret, and the sorcerers cannot overcome it."
