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
