It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Read the Qur'an, for it will come on the Day of Resurrection as an intercessor for those who read it. And hold fast to the two radiant surahs: Surah al-Baqarah and Surah Al Imran, for on the Day of Resurrection they will both come as though they were two clouds, or two canopies, or two flocks of birds in ranks, pleading on behalf of the one who read them on the Day of Resurrection. Read Surah al-Baqarah, for embracing it is a blessing and abandoning it is a source of regret, and the sorcerers cannot overcome it."
