Sunan an-Nasa'i 757
Narrated Abu Saeed:
It was narrated from Abu Saeed that the  Messenger of Allah(ﷺ) said: " If anyone of you is praying, he should not let anyone pass in front of him, and if he insists (on passing) then let him fight him."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي سَعِيدٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَدَعْ أَحَدًا أَنْ يَمُرَّ بَيْنَ يَدَيْهِ فَإِنْ أَبَى فَلْيُقَاتِلْهُ ‏"‏ ‏.‏
