When one of you prays, he should not let anyone pass in front of him; he should turn him away as far as possible; but if he refuses (to go), he should fight him, for he is only a devil. (Using translation from Abū Dāʾūd 697)
"إذا كانَ أحدُكُمْ يُصَلِّي فلا يَدعْ أحدًا يَمرّ بين يديه، فإِنْ أبَى فليقاتِله، فإِنَّ معَه القرينَ".
