Virtues of the Qur'an's Chapters and Verses 14
Abdullah b. Masʿūd (RA) reported that the Prophet ﷺ said:
“Whoever reads the last two verses from Sūrat al-Baqarah at night, they will be sufficient for him.” Reference: Sahih al-Bukhari 5009

Regarding the word ‘sufficient’ in the hadith, Imam al-Nawawi (RA) says: It was said (by scholars) that it means it will suffice him from the night prayer, and others said it means as a protection against the devils, and yet others said it means protection against harmful animals, and it is likely encompassing of all these things (and more).”

Ibn Ḥajar states: “[It] was explicitly reported by ʿĀsim from ʿAlqamah from Ibn Masʿūd, “Whoever recites (the two verses at) the end of Sūrat al-Baqarah, it will be sufficient for him instead of standing in prayer for one night.”

عَنْ أَبِي مَسْعُودٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ مَنْ قَرَأَ بِالآيَتَيْنِ مِنْ آخِرِ سُورَةِ الْبَقَرَةِ فِي لَيْلَةٍ كَفَتَاهُ‏ "‏‏.‏
