Yahya related to me from Malik from Zayd ibn Aslam from Abd ar- Rahman ibn Abi Said al-Khudri from his father that the Messenger of Allah ﷺ said, "Do not let anyone pass in front of you when you are praying. Repel him as much as you can, and, if he refuses, fight him, for he is only a shaytan."  

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

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah from Busr ibn Said that Zayd ibn Khalid al-Juhani sent him to Abu Juhaym to ask him what he had heard from the Messenger of Allah ﷺ about passing in front of someone praying. Abu Juhaym said, "The Messenger of Allah ﷺ said, 'If the one who passes in front of a man praying knew what he was bringing upon himself it would be better for him to stop for forty than to pass in front of him.' " Abu'n-Nadr said, "I do not know whether he said forty days or months or years."  

سَمِعَ مِنْ رَسُولِ اللَّهِ ﷺ فِي الْمَارِّ بَيْنَ يَدَىِ الْمُصَلِّي فَقَالَ أَبُو جُهَيْمٍ قَالَ رَسُولُ اللَّهِ ﷺ لَوْ يَعْلَمُ الْمَارُّ بَيْنَ يَدَىِ الْمُصَلِّي مَاذَا عَلَيْهِ لَكَانَ أَنْ يَقِفَ أَرْبَعِينَ خَيْرًا لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ قَالَ أَبُو النَّضْرِ لاَ أَدْرِي أَقَالَ أَرْبَعِينَ يَوْمًا أَوْ شَهْرًا أَوْ سَنَةً  

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that Kab al-Ahbar said, "If the person who passed in front of a man praying knew what he was bringing on himself, it would be better for him to sink into the ground than to pass in front of him."  

قَالَ لَوْ يَعْلَمُ الْمَارُّ بَيْنَ يَدَىِ الْمُصَلِّي مَاذَا عَلَيْهِ لَكَانَ أَنْ يُخْسَفَ بِهِ خَيْرًا لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ  

Yahya related to me from Malik that he had heard that Abdullah ibn Umar used to disapprove of passing in front of women while they were praying.  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ يَكْرَهُ أَنْ يَمُرَّ بَيْنَ أَيْدِي النِّسَاءِ وَهُنَّ يُصَلِّينَ  

Yahya related to me from Malik from Nafi that Abdullah ibn Umar would neither pass in front of anyone, nor let anyone pass in front of him.  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ لاَ يَمُرُّ بَيْنَ يَدَىْ أَحَدٍ وَلاَ يَدَعُ أَحَدًا يَمُرُّ بَيْنَ يَدَيْهِ
