Narrated Abu Said Al-Khudri:
حَدَّثَنَا أَبُو مَعْمَرٍ ، حَدَّثَنَا عَبْدُ الْوَارِثِ ، حَدَّثَنَا يُونُسُ ، عَنْ حُمَيْدِ بْنِ هِلاَلٍ ، عَنْ أَبِي صَالِحٍ ، عَنْ أَبِي سَعِيدٍ ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " إِذَا مَرَّ بَيْنَ يَدَىْ أَحَدِكُمْ شَىْءٌ وَهُوَ يُصَلِّي فَلْيَمْنَعْهُ، فَإِنْ أَبَى فَلْيَمْنَعْهُ، فَإِنْ أَبَى فَلْيُقَاتِلْهُ، فَإِنَّمَا هُوَ شَيْطَانٌ " .
The Prophet (ﷺ) said, "If while you are praying, somebody intends to pass in front of you, prevent him; and should he insist, prevent him again; and if he insists again, fight with him (i.e. prevent him violently e.g. pushing him violently), because such a person is (like) a devil."
