Sayyiduna Shaddad bin Aws (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: "Allah, the Mighty and Majestic, wrote a Book two thousand years before He created the heavens and the earth, and He sent down in it two verses with which He concluded Surah al-Baqarah. In whatever house they are recited for three nights, no devil comes near it."
