Abu Mas'ud Al-Ansari Radiyallahu 'anhu narrates that Rasullullah Sallallahu 'alaihi wasallam said: He who recites the last two verses of Surah Al-Baqarah at night, these will suffice for him. (Tirmidhi: 2881)
Note: These two verses will suffice means: 1. He will be protected
from every evil throughout the night. 2. The reward of reciting these
two verses will be as much as that of Tahajjud. (Nawawi)
