Surat Al-Bakara

Abdullah ibn Mas’ud (radiAllahu anhu) said, ‘Whoever recited ten verses from al-Baqarah in the night, Satan shall not have access to that house, during the night till he wakes in the morning. These are: Four from the first part of the Surah, followed by the verse of the Throne, two verses after the verse of the Throne and three from the last part of the Surah’.
