Abu Huraira said, "Messenger of Allah ﷺ put me in charge of the Zakat of Ramadan (i.e. Zakat-ul-Fitr). Someone came to me and started scooping some of the foodstuff of (Zakat) with both hands. I caught him and told him that I would take him to Messenger of Allah ﷺ." Then Abu Huraira told the whole narration and added "He (i.e. the thief) said, 'Whenever you go to your bed, recite the Verse of "Al-Kursi" (2.255) for then a guardian from Allah will be guarding you, and Satan will not approach you till dawn.' " On that the Prophet ﷺ said, "He told you the truth, though he is a liar, and he (the thief) himself was the Satan."
وَكَّلَنِي رَسُولُ اللَّهِ ﷺ بِحِفْظِ زَكَاةِ رَمَضَانَ فَأَتَانِي آتٍ فَجَعَلَ يَحْثُو مِنَ الطَّعَامِ فَأَخَذْتُهُ فَقُلْتُ لأَرْفَعَنَّكَ إِلَى رَسُولِ اللَّهِ ﷺ فَذَكَرَ الْحَدِيثَ فَقَالَ إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَاقْرَأْ آيَةَ الْكُرْسِيِّ لَنْ يَزَالَ عَلَيْكَ مِنَ اللَّهِ حَافِظٌ وَلاَ يَقْرَبُكَ شَيْطَانٌ حَتَّى تُصْبِحَ فَقَالَ النَّبِيُّ ﷺ صَدَقَكَ وَهْوَ كَذُوبٌ ذَاكَ شَيْطَانٌ
