Hadith Q816
وَإِبَاحَةِ قِتَالِهِ بِالْيَدِ إِنْ أَبَى الْمَارُّ الِامْتِنَاعَ مِنَ الْمُرُورِ، بِذِكْرِ خَبَرٍ مُجْمَلٍ غَيْرِ مُفَسَّرٍ
And if the passerby does not stop despite being prevented, then it is permissible to fight him with the hand. In this regard, a concise, unexplained narration is mentioned.
Hadith 816
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When any one of you is performing prayer, he should not allow anyone to pass in front of him. If the person refuses (to stop and insists on passing), then he should fight him, for he is a devil."
