Whoever recites two verses ... (text as in the following hadith)  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ قَرَأَ بِالآيَتَيْنِ  

The Prophet ﷺ said, "If somebody recited the last two Verses of Surat Al-Baqara at night, that will be sufficient for him."  

قَالَ النَّبِيُّ ﷺ مَنْ قَرَأَ بِالآيَتَيْنِ مِنْ آخِرِ سُورَةِ الْبَقَرَةِ فِي لَيْلَةٍ كَفَتَاهُ  

Messenger of Allah ﷺ ordered me to guard the Zakat revenue of Ramadan. Then somebody came to me and started stealing from the foodstuff. I caught him and said, "I will take you to Messenger of Allah ﷺ!" Then Abu Huraira described the whole narration and said: That person said (to me), "(Please don't take me to Messenger of Allah ﷺ and I will tell you a few words by which Allah will benefit you.) When you go to your bed, recite Ayat-al-Kursi, (2.255) for then there will be a guard from Allah who will protect you all night long, and Satan will not be able to come near you till dawn." (When the Prophet ﷺ heard the story) he said (to me), "He (who came to you at night) told you the truth although he is a liar; and it was Satan."  

وَكَّلَنِي رَسُولُ اللَّهِ ﷺ بِحِفْظِ زَكَاةِ رَمَضَانَ فَأَتَانِي آتٍ فَجَعَلَ يَحْثُو مِنَ الطَّعَامِ فَأَخَذْتُهُ فَقُلْتُ لأَرْفَعَنَّكَ إِلَى رَسُولِ اللَّهِ ﷺ فَقَصَّ الْحَدِيثَ فَقَالَ إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَاقْرَأْ آيَةَ الْكُرْسِيِّ لَنْ يَزَالَ مَعَكَ مِنَ اللَّهِ حَافِظٌ وَلاَ يَقْرَبُكَ شَيْطَانٌ حَتَّى تُصْبِحَ وَقَالَ النَّبِيُّ ﷺ صَدَقَكَ وَهْوَ كَذُوبٌ ذَاكَ شَيْطَانٌ
