Is brandishing a drawn sword forbidden or reprehensible, and is its doer cursed if it is forbidden, and does the ruling apply to knives, sharp objects, and pistols?

Islam forbade carrying a drawn sword because of the danger of harm it poses, and this is a matter of etiquette and disapproval. This prohibition extends to everything whose harm is feared, such as knives, sharp tools, and firearms. Therefore, they must be held in a way that does not harm others, such as holding a knife by its blunt end, sheathing a sword before handing it over, and holding the tips of arrows. This is part of the etiquette that prevents harm and damage.
