عَن أَبي هُرَيْرَةَ رضي الله عنه عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ:
«لاَ يُشِيرُ أَحَدُكُمْ عَلَى أَخِيهِ بِالسِّلاَحِ، فَإِنَّهُ لاَ يَدْرِي، لَعَلَّ الشَّيْطَانَ يَنْزِعُ فِي يَدِهِ، فَيَقَعُ فِي حُفْرَةٍ مِنَ النَّارِ».
[صحيح] - [متفق عليه] - [صحيح البخاري: 7072]

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said:
"None of you should point a weapon at his brother, for he does not know; perhaps the devil causes his hand to slip, and then he falls into a pit of the Fire."
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 7072]
The Prophet (may Allah's peace and blessings be upon him) warned that a Muslim should not point any type of weapon at his fellow Muslim, as he does not know; perhaps the devil incites him to move the weapon in his hand, thus, will kill or harm his brother. This would result in committing a sin that would cause him to fall into a pit of the Fire.
