Re: Islamic aspect of wearing a Tie.
In olden days in Europe, soldiers used to wear a scarf around their neck to wipe the blood off (from the battle wounds). Later, on their return, they used to parade in the blood stained scarf, which used to be looked as a badge of honor and bravery in that society. That scarf was replaced as by a symbolic neckwear that latter evolved into what we known as tie.
