حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَدَعْ أَحَدًا يَمُرُّ بَيْنَ يَدَيْهِ وَلْيَدْرَأْهُ مَا اسْتَطَاعَ فَإِنْ أَبَى فَلْيُقَاتِلْهُ فَإِنَّمَا هُوَ شَيْطَانٌ ‏"‏ ‏.‏

Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying

When any one of you prays, let him not allow anyone to pass in front of him, and let him ward him off as much as he can. If he refuses, then let him fight him, for indeed he is a devil.
