Hadith 9:38
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, may Allah bless him and grant him peace, 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."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنْ أَبِيهِ، 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 "
