The Prophet ﷺ said, (what is ascribed to him in the following Hadith): Narrated Abu Salih As-Samman: I saw Abu Saʿid Al-Khudri praying on a Friday, behind something which acted as a Sutra. A young man from Bani Abi Mu'ait [??] , wanted to pass in front of him, but Abu Saʿid repulsed him with a push on his chest. Finding no alternative he again tried to pass but Abu Saʿid pushed him with a greater force. The young man abused Abu Saʿid and went to Marwan and lodged a complaint against Abu Saʿid and Abu Saʿid followed the young man to Marwan who asked him, "O Abu Saʿid! What has happened between you and the son of your brother?" Abu Saʿid said to him, "I heard the Prophet ﷺ saying, 'If anybody amongst you is praying behind something as a Sutra and somebody tries to pass in front of him, then he should repulse him and if he refuses, he should use force against him for he is a Shaitan (a Satan).' "  

قَالَ النَّبِيُّ ﷺ وَحَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ قَالَ حَدَّثَنَا حُمَيْدُ بْنُ هِلاَلٍ الْعَدَوِيُّ قَالَ حَدَّثَنَا أَبُو صَالِحٍ السَّمَّانُ قَالَ رَأَيْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ فِي يَوْمِ جُمُعَةٍ يُصَلِّي إِلَى شَىْءٍ يَسْتُرُهُ مِنَ النَّاسِ فَأَرَادَ شَابٌّ مِنْ بَنِي أَبِي مُعَيْطٍ أَنْ يَجْتَازَ بَيْنَ يَدَيْهِ فَدَفَعَ أَبُو سَعِيدٍ فِي صَدْرِهِ فَنَظَرَ الشَّابُّ فَلَمْ يَجِدْ مَسَاغًا إِلاَّ بَيْنَ يَدَيْهِ فَعَادَ لِيَجْتَازَ فَدَفَعَهُ أَبُو سَعِيدٍ أَشَدَّ مِنَ الأُولَى فَنَالَ مِنْ أَبِي سَعِيدٍ ثُمَّ دَخَلَ عَلَى مَرْوَانَ فَشَكَا إِلَيْهِ مَا لَقِيَ مِنْ أَبِي سَعِيدٍ وَدَخَلَ أَبُو سَعِيدٍ خَلْفَهُ عَلَى مَرْوَانَ فَقَالَ مَا لَكَ وَلاِبْنِ أَخِيكَ يَا أَبَا سَعِيدٍ قَالَ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِذَا صَلَّى أَحَدُكُمْ إِلَى شَىْءٍ يَسْتُرُهُ مِنَ النَّاسِ فَأَرَادَ أَحَدٌ أَنْ يَجْتَازَ بَيْنَ يَدَيْهِ فَلْيَدْفَعْهُ فَإِنْ أَبَى فَلْيُقَاتِلْهُ فَإِنَّمَا هُوَ شَيْطَانٌ  

I narrate to you what I heard and saw from Abu Sa'id al-Khudri: One day I was with Abu Sa'id and he was saying prayer on Friday turning to a thing which concealed him from the people when a young man from Banu Mu'ait came there and he tried to pass in front of him; he turned him back by striking his chest. He looked about but finding no other way to pass except in front of Abu Sa'id, made a second attempt. He (Abu Sa'id) turned him away by Striking his chest more vigorously than the first stroke. He stood up and had a scuffle with Abu Sa'id. Then the people gathered there He came out and went to Marwan and complained to him what had happened to him. Abu Sa'id too came to Marwan. Marwin said to him: What has happened to you and the son of your brother that he came to complain against you? Abu Sa'id said: I heard from the Messenger of Allah ﷺ saying: When any one of you prays facing something which conceals him from people and anyone tries to pass in front of him, he should be turned away, but if he refuses, he should be forcibly restrained from it, for he is a devil. (Using translation from Muslim 505b)   

بَيْنَمَا أَنَا مَعَ أَبِي سَعِيدٍ نُصَلِّي يَوْمَ الْجُمُعَةِ إِلَى شَيْءٍ يَسْتُرُهُ مِنَ النَّاسِ إِذْ دَخَلَ شَابٌّ مِنْ بَنِي أَبِي مُعَيْطٍ أَرَادَ أَنْ يَجْتَازَ بَيْنَ يَدَيْهِ فَدَفَعَ نَحْرَهُ فَنَظَرَ فَلَمْ يَرَ مَسَاغًا إِلَّا بَيْنَ يَدَيْ أَبِي سَعِيدٍ فَأَعَادَ فَدَفَعَ فِي نَحِرِهِ أَشَدَّ مِنَ الدَّفْعَةِ الْأُولَى فَمَثُلَ قَائِمًا وَنَالَ مِنْ أَبِي سَعِيدٍ ثُمَّ زَاحَمَ النَّاسَ فَخَرَجَ فَدَخَلَ عَلَى مَرْوَانَ فَشَكَا إِلَيْهِ مَا لَقِيَ قَالَ وَدَخَلَ أَبُو سَعِيدٍ عَلَى مَرْوَانَ فَقَالَ لَهُ مَرْوَانُ مَا لَكُ وَلِابْنِ أَخِيكَ جَاءَ يَشْتَكِيكَ؟ فَقَالَ أَبُو سَعِيدٍ ؓ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِذَا صَلَّى أَحَدُكُمْ إِلَى شَيْءٍ يَسْتُرُهُ مِنَ النَّاسَ فَأَرَادَ أَحَدٌ أَنْ يَجْتَازَ بَيْنَ يَدَيْهِ فَلْيَدْفَعْ فِي نَحْرِهِ فَإِنْ أَبَى فَلْيُقَاتِلْهُ فَإِنَّمَا هُوَ شَيْطَانٌ
