Hadith 100
قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لا يُشِيرُ أَحَدُكُمْ إِلَى أَخِيهِ بِالسِّلاحِ، فَإِنَّهُ لا يَدْرِي أَحَدُكُمْ لَعَلَّ الشَّيْطَانَ أَنْ يَنْزِعَ فِي يَدِهِ، فَيَقَعَ فِي حُفْرَةٍ مِنَ النَّارِ "
And the Messenger of Allah, peace and blessings be upon him, said: "None of you should point a weapon at his brother, (because) he does not know that perhaps Satan may cause the weapon to slip from his hand (and he may kill someone), as a result of which he (the killer) will fall into a pit of Hell."
