The Prophet ﷺ said, "None of you should point out towards his Muslim brother with a weapon, for he does not know, Satan may tempt him to hit him and thus he would fall into a pit of fire (Hell)"
عَنِ النَّبِيِّ ﷺ قَالَ لاَ يُشِيرُ أَحَدُكُمْ عَلَى أَخِيهِ بِالسِّلاَحِ فَإِنَّهُ لاَ يَدْرِي لَعَلَّ الشَّيْطَانَ يَنْزِعُ فِي يَدِهِ فَيَقَعُ فِي حُفْرَةٍ مِنَ النَّارِ
