Narrated Abu Huraira:
Allah's Apostle deputed me to keep Sadaqat (al-Fitr) of Ramadan. A comer came and started taking handfuls of the foodstuff (of the Sadaqa) (stealthily). I took hold of him and said, "By Allah, I will take you to Allah's Apostle ." He said, "I am needy and have many dependents, and I am in great need." I released him, and in the morning Allah's Apostle asked me, "What did your prisoner do yesterday?" I said, "O Allah's Apostle! The person complained of being needy and of having many dependents, so, I pitied him and let him go." Allah's Apostle ﷺ said, "Indeed, he told you a lie and he will be coming again." I believed that he would show up again as Allah's Apostle had told me that he would return. So, I waited for him watchfully. When he (showed up and) started stealing handfuls of foodstuff, I caught hold of him again and said, "I will definitely take you to Allah's Apostle. He said, "Leave me, for I am very needy and have many dependents. I promise I will not come back again." I pitied him and let him go. In the morning Allah's Apostle asked me, "What did your prisoner do." I replied, "O Allah's Apostle! He complained of his great need and of too many dependents, so I took pity on him and set him free." Allah's Apostle ﷺ said, "Verily, he told you a lie and he will return." I waited for him attentively for the third time, and when he (came and) started stealing handfuls of the foodstuff, I caught hold of him and said, "I will surely take you to Allah's Apostle as it is the third time you promise not to return, yet you break your promise and come." He said, "(Forgive me and) I will teach you some words with which Allah will benefit you." I asked, "What are they?" He replied, "Whenever you go to bed, recite "Ayat-al-Kursi"-- 'Allahu la ilaha illa huwa-l-Haiy-ul Qaiyum' till you finish the whole verse. (If you do so), Allah will appoint a guard for you who will stay with you and no satan will come near you till morning. " So, I released him. In the morning, Allah's Apostle asked, "What did your prisoner do yesterday?" I replied, "He claimed that he would teach me some words by which Allah will benefit me, so I let him go." Allah's Apostle asked, "What are they?" I replied, "He said to me, 'Whenever you go to bed, recite Ayat-al-Kursi from the beginning to the end ---- Allahu la ilaha illa huwa-lHaiy-ul-Qaiyum----.' He further said to me, '(If you do so), Allah will appoint a guard for you who will stay with you, and no satan will come near you till morning.' (Abu Huraira or another sub-narrator) added that they (the companions) were very keen to do good deeds. The Prophet ﷺ said, "He really spoke the truth, although he is an absolute liar. Do you know whom you were talking to, these three nights, O Abu Huraira?" Abu Huraira said, "No." He said, "It was Satan."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي قَدْ وَهَبْتُ لَكَ مِنْ نَفْسِي. فَقَالَ رَجُلٌ زَوِّجْنِيهَا. قَالَ
" قَدْ زَوَّجْنَاكَهَا بِمَا مَعَكَ مِنَ الْقُرْآنِ ".
