Two people disagree strongly. One threatens the other with a weapon to force agreement, replacing discussion with fear. The phrase عَلَيْنَا السِّلَاحَ explicitly concerns weapons directed “against us”; it should not be flattened into ordinary disagreement or every instance of legitimate safety precautions.
Example 1: Address a dispute through discussion, mediation, and proper channels for complaints.
Example 2: When danger arises, prioritize immediate safety and seek appropriate lawful assistance.
Opposing someone's argument is not the same as threatening unlawful harm. The narration draws attention to the seriousness of crossing that boundary.
