When one of you prays, he should not let anyone pass in front of him; he should turn him away as far as possible; but if he refuses (to go), he should fight him, for he is only a devil. (Using translation from Abū Dāʾūd 697)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلَا يَدَعْ أَحَدًا يَمُرُّ بَيْنَ يَدَيْهِ وَلْيَدْرَأْهُ مَا اسْتَطَاعَ فَإِنْ أَبَى فَلْيُقَاتِلْهُ فَإِنَّمَا هُوَ شَيْطَانٌ  

When one of you prays, he should pray facing the sutrah (screen or covering) and he should keep himself close to it. He then narrated the tradition to the same effect. (Using translation from Abū Dāʾūd 698)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ فَلْيُصَلِّ إِلَى سُتْرَةٍ وَلْيَدْنُ مِنْهَا ثُمَّ سَاقَ مَعْنَاهُ  

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  

[Machine] Abu Sa'id Al-Khudri used to pray, and a man from the family of Abu Mu'ayt passed by and he prevented him. But the man refused to stop, so Abu Sa'id threw him away. Marwan was the governor of Madinah at that time, so the man complained to him about what happened. Marwan mentioned this incident to Abu Sa'id, who said, "The Messenger of Allah ﷺ said, 'If something passes in front of one of you while he is praying, let him prevent it. And if it insists, let him fight it, for it is only a Shaytan (devil).' And I had forbidden him, but he refused to stop."  

أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ كَانَ يُصَلِّي فَمَرَّ رَجُلٌ مِنْ آلِ أَبِي مُعَيْطٍ فَمَنَعَهُ فَأَبَى أَنْ يَنْتَهِيَ فَنَبَذَهُ فَأَبَى فَدَفَعَ فِي صَدْرِهِ وَمَرْوَانُ يَوْمَئِذٍ أَمِيرٌ عَلَى الْمَدِينَةِ فَشَكَا ذَلِكَ إِلَيْهِ فَذَكَرَ ذَلِكَ مَرْوَانُ لِأَبِي سَعِيدٍ فَقَالَ أَبُو سَعِيدٍ قَالَ رَسُولُ اللهِ ﷺ إِذَا مَرَّ بَيْنَ يَدَيْ أَحَدِكُمْ شَيْءٌ وَهُوَ يُصَلِّي فَلْيَمْنَعْهُ فَإِنْ أَبِي فَلْيُقَاتِلْهُ فَإِنَّمَا هُوَ شَيْطَانٌ وَإِنِّي قَدْ كُنْتُ نَهَيْتُهُ فَأَبَى أَنْ يَنْتَهِيَ  

[Machine] The Messenger of Allah ﷺ said, "Do not pray except behind a barrier, and do not allow anyone to pass in front of you. If they refuse, then fight them because they have a companion with them."  

قَالَ رَسُولُ اللهِ ﷺ لَا تُصَلُّوا إِلَّا إِلَى سُتْرَةٍ وَلَا تَدَعْ أَحَدًا يَمُرُّ بَيْنَ يَدَيْكَ فَإِنْ أَبَى فَقَاتِلْهُ فَإِنَّ مَعَهُ الْقَرِينُ  

The Prophet ﷺ was (once) praying. A kid went passing in front of him and he kept on stopping it. (Using translation from Abū Dāʾūd 709)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُصَلِّي فَأَرَادَ جَدْيٌ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ فَجَعَلَ يَتَّقِيهِ  

We came down from the mountain pass of Adhaakhir in the company of the Messenger of Allah ﷺ. The time of prayer came and he prayed facing a direction of prayer, and we were (standing) behind him. Then a kid came and passed in front of him. He kept on stopping it until he brought his stomach near the wall (to detain it), and at last it passed behind him, or as Musaddad said. (Using translation from Abū Dāʾūd 708)   

هَبَطْنَا مَعَ رَسُولِ اللهِ ﷺ مِنْ ثَنِيَّةٍ أَذَاخِرَ فَحَضَرَتِ الصَّلَاةُ فَصَلَّى إِلَى جِدَارٍ فَاتَّخَذَهُ قِبْلَةً وَنَحْنُ خَلْفَهُ فَجَاءَتْ بَهْمَةٌ لَتَمُرَّ بَيْنَ يَدَيْهِ فَمَا زَالَ يُدَارِيهَا حَتَّى لَصَقَ بَطْنُهُ بِالْجِدَارِ وَمَرَّتْ مِنْ وَرَائِهِ
