From Sahih Muslim (Hadith 1880):
Abu Mas'ud reported Allah's Messenger (ﷺ) as saying:If anyone recites the two verses at the end of Surah al-Baqara at night, they would suffice for him 'Abd al-Rahman said: I met Abu Mas'ud and he was circumambulating the House (of Allah) and asked him about this (tradition) and he narrated it to me from the Messenger of Allah (ﷺ)
