Nu'man ibne-Bashir Radiyallahu 'anhuma narrates Rasullullah Sallallahu 'alaihi wasallam said: Indeed Allah inscribed a book, two thousand years before creating the heavens and the earth. He sent down two verses with which He ended Surah Al-Baqarah. When these verses are being recited in a house for three nights, Shaitan will not come near it. (Tirmidhi: 2882)
