Whoever carries weapons against us is not one of us
Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) said:
"Whoever carries weapons against us is not one of us."
«مَنْ حَمَلَ عَلَيْنَا السِّلَاحَ فَلَيْسَ مِنَّا».
The Prophet (may Allah's peace and blessings be upon him) warns against carrying weapons against Muslims to intimidate or rob them. Whoever does so unjustly has committed a serious crime and a major sin and deserves this stern warning.
من حمل علينا السلاح: المقصود به من حمل السلاح؛ لقتال المسلمين أو لإرهاربهم.
The Hadīth gives a stern warning against Muslims fighting one another.
One of the most mischievous acts on earth is to brandish weapons against Muslims and cause corruption by killing.
The warning in question does not apply to just fighting, such as fighting the oppressors, corruptors, and the like.
It is prohibited to scare Muslims with weapons and the like, even if done jokingly.
