وعن أَبي هريرة - ﵁ - قَالَ: وَكَّلَنِي رسولُ الله - ﷺ - بِحِفْظِ زَكَاةِ رَمَضَانَ، فَأتَانِي آتٍ فَجَعَلَ يَحْثُو مِنَ الطَّعَام، فَأخَذْتُهُ فقُلتُ: لأَرْفَعَنَّكَ إِلَى رسولِ الله - ﷺ - قَالَ: إنِّي مُحْتَاجٌ، وَعَليَّ عِيَالٌ، وَبِي حَاجَةٌ شَدِيدَةٌ، فَخَلَّيْتُ عَنْهُ، فَأصْبَحْتُ، فَقَالَ رسول الله - ﷺ: «يَا أَبَا هُريرة، مَا فَعَلَ أَسِيرُكَ البَارِحَةَ؟» قُلْتُ: يَا رسول الله، شَكَا حَاجَةً وَعِيَالًا، فَرحِمْتُهُ فَخَلَّيْتُ سَبيلَهُ. فَقَالَ: «أمَا إنَّهُ قَدْ كَذَبَكَ وَسَيَعُودُ» فَعَرَفْتُ أنَّهُ سَيَعُودُ، لقولِ رسول الله - ﷺ - فَرَصَدْتُهُ، فَجاء يَحْثُو مِنَ الطَّعَامِ، فَقُلتُ: لأَرْفَعَنَّكَ إِلَى رسول الله - ﷺ - قَالَ: دَعْنِي فَإنِّي مُحْتَاجٌ، وَعَلَيَّ عِيَالٌ لاَ أعُودُ، فَرحِمْتُهُ فَخَلَّيْتُ سَبيلَهُ، فَأصْبَحْتُ فَقَالَ لي رسول الله - ﷺ: «يَا أَبَا هُريرة، مَا فَعَلَ أَسِيرُكَ البَارِحَةَ؟» قُلْتُ: يَا رسول الله، شَكَا حَاجَةً وَعِيَالًا، فَرحِمْتُهُ فَخَلَّيْتُ سَبيلَهُ. فَقَالَ: «إنَّهُ قَدْ كَذَبَكَ وَسَيَعُودُ» فَرَصَدْتُهُ الثَّالثَة، فَجاء يَحْثُو مِنَ الطَّعَامِ فَأخَذْتُهُ، فَقُلتُ: لأَرْفَعَنَّكَ إِلَى رسولِ الله - ﷺ - وهذا آخِرُ ثلاثِ مَرَّاتٍ أنَّكَ تَزْعُمُ أنَّكَ لاَ تَعُودُ! فَقَالَ: دَعْنِي فَإنِّي أُعَلِّمُكَ كَلِمَاتٍ يَنْفَعُكَ اللهُ بِهَا، قُلْتُ: مَا هُنَّ؟ قَالَ: إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَاقْرَأْ آيَةَ الكُرْسِيِّ، فَإنَّهُ لَنْ يَزَالَ عَلَيْكَ مِنَ الله حَافِظٌ، وَلاَ يَقْرَبُكَ شَيْطَانٌ حَتَّى تُصْبِحَ، فَخَلَّيْتُ سَبِيلَهُ، فَأصْبَحْتُ، فَقَالَ لي رسولُ الله - ﷺ: «مَا فَعَلَ أسِيرُكَ البَارِحَةَ؟» قُلْتُ: يَا رسول الله، زَعَمَ أنَّهُ يُعَلِّمُنِي كَلِمَاتٍ يَنْفَعُنِي اللهُ بِهَا، فَخَلَّيْتُ سَبيلَهُ، قَالَ: «مَا هِيَ؟» قُلْتُ: قَالَ لي: إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَاقْرَأْ آيَة الكُرْسِيِّ مِنْ أوَّلِهَا حَتَّى تَخْتِمَ الآية: ﴿اللهُ لاَ إلَهَ إِلاَّ هُوَ الحَيُّ القَيُّومُ﴾ وقال لِي: لاَ يَزَالُ عَلَيْكَ مِنَ اللهِ حَافِظٌ، وَلَنْ يَقْرَبَكَ شَيْطَانٌ حَتَّى تُصْبِحَ. فَقَالَ النبيُّ - ﷺ: «أمَا إنَّهُ قَدْ صَدَقَكَ وَهُوَ كَذُوبٌ، تَعْلَمُ مَنْ تُخَاطِبُ مُنْذُ ثَلاَثٍ يَا أَبَا هُرَيْرَةَ؟» قُلْتُ: لاَ. قَالَ: «ذَاكَ شَيْطَانٌ». رواه البخاري.
From Abū Hurayra (may Allah be pleased with him), who said: The Messenger of Allah (ﷺ) put me in charge of guarding the zakāt of Ramadan. Someone came and began scooping up the food, so I seized him and said, "I will surely take you to the Messenger of Allah (ﷺ)." He said, "I am needy, I have dependants, and I am in great need," so I let him go. In the morning the Messenger of Allah (ﷺ) said, "O Abū Hurayra, what did your captive do last night?" I said, "O Messenger of Allah, he complained of need and dependants, so I had mercy on him and set him free." He said, "Indeed he lied to you, and he will return." So I knew he would return, because of the words of the Messenger of Allah (ﷺ). I watched for him, and he came scooping up the food. I said, "I will surely take you to the Messenger of Allah (ﷺ)." He said, "Let me go, for I am needy and have dependants; I will not return," so I had mercy on him and set him free. In the morning the Messenger of Allah (ﷺ) said to me, "O Abū Hurayra, what did your captive do last night?" I said, "O Messenger of Allah, he complained of need and dependants, so I had mercy on him and set him free." He said, "Indeed he lied to you, and he will return." I watched for him the third time, and he came scooping up the food. I seized him and said, "I will surely take you to the Messenger of Allah (ﷺ) — this is the last of three times: each time you claim you will not return!" He said, "Let me go, and I will teach you some words by which Allah will benefit you." I said, "What are they?" He said, "When you go to your bed, recite Āyat al-Kursī, for then a guardian from Allah will remain over you, and no devil will come near you until morning." So I set him free. In the morning the Messenger of Allah (ﷺ) said to me, "What did your captive do last night?" I said, "O Messenger of Allah, he claimed he would teach me some words by which Allah would benefit me, so I set him free." He said, "What were they?" I said, "He told me: when you go to your bed, recite Āyat al-Kursī from its beginning until you complete the verse, 'Allah — there is no deity except Him, the Ever-Living, the Sustainer,' and he told me a guardian from Allah will remain over you, and no devil will come near you until morning." The Prophet (ﷺ) said, "Indeed he told you the truth, though he is an inveterate liar. Do you know whom you have been speaking with these three nights, O Abū Hurayra?" I said, "No." He said, "That was a devil." Narrated by al-Bukhārī.
