(110) باب مَا يُؤْمَرُ الْمُصَلِّي أَنْ يَدْرَأَ عَنِ الْمَمَرِّ بَيْنَ يَدَيْهِ
Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying:
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.
