Sahih Muslim 807 a
'Abd al-Rahman b. Yazid reported:
I met Abu Mas'ud near the House (Ka'ba) and said to him: A hadith has been conveyed to me on your authority about the two (concluding verses of Surah al-Baqara. He said: Yes. The Messenger of Allah (ﷺ) (in fact) said: Anyone who recites the two verses at the end of Surah al-Baqara at night, they would suffice for him.
وَحَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا مَنْصُورٌ، عَنْ إِبْرَاهِيمَ، عَنْ عَبْدِ الرَّحْمَنِ، بْنِ يَزِيدَ قَالَ لَقِيتُ أَبَا مَسْعُودٍ عِنْدَ الْبَيْتِ فَقُلْتُ حَدِيثٌ بَلَغَنِي عَنْكَ فِي الآيَتَيْنِ فِي سُورَةِ الْبَقَرَةِ ‏.‏ فَقَالَ نَعَمْ ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ الآيَتَانِ مِنْ آخِرِ سُورَةِ الْبَقَرَةِ مَنْ قَرَأَهُمَا فِي لَيْلَةٍ كَفَتَاهُ ‏"‏ ‏.‏
