Sahih Muslim 808a
Abu Mas'ud reported Messenger of Allah 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 Apostle of Allah ﷺ.
حَدَّثَنَا مِنْجَابُ بْنُ الْحَارِثِ التَّمِيمِيُّ، أَخْبَرَنَا ابْنُ مُسْهِرٍ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، عَنْ عَلْقَمَةَ بْنِ قَيْسٍ، عَنْ أَبِي مَسْعُودٍ الأَنْصَارِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنْ قَرَأَ هَاتَيْنِ الآيَتَيْنِ مِنْ آخِرِ سُورَةِ الْبَقَرَةِ فِي لَيْلَةٍ كَفَتَاهُ " . قَالَ عَبْدُ الرَّحْمَنِ فَلَقِيتُ أَبَا مَسْعُودٍ وَهُوَ يَطُوفُ بِالْبَيْتِ فَسَأَلْتُهُ فَحَدَّثَنِي بِهِ عَنِ النَّبِيِّ ﷺ .
