Abu Huraira reported a hadith from Allah's Messenger (ﷺ) ; (one of them was this) that Allah's Messenger (ﷺ) said: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.
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يُشِيرُ أَحَدُكُمْ إِلَى أَخِيهِ بِالسِّلاَحِ فَإِنَّهُ لاَ يَدْرِي أَحَدُكُمْ لَعَلَّ الشَّيْطَانَ يَنْزِعُ فِي يَدِهِ فَيَقَعُ فِي حُفْرَةٍ مِنَ النَّارِ " .
