None amongst you should point a weapon towards his brother, for he does not know that Satan might cause the weapon (to slip) from his hand and (he may injure anyone) and thus he may fall into Hell-Fire. (Using translation from Muslim 2617)
وَقَالَ رَسُولُ اللهِ ﷺ لَا يَمْشِيَنَّ أَحَدُكُمْ إِلَى أَخِيهِ بِالسِّلَاحِ فَإِنَّهُ لَا يَدْرِي أَحَدُكُمْ لَعَلَّ الشَّيْطَانَ يَنْزِعُ فِي يَدِهِ فَيَقَعُ فِي حُفْرَةٍ مِنْ نَارٍ
