What is the ruling on men wearing neckties made of 100% silk or silk mixed with synthetic fibers, and is it permissible to gift a silk necktie to a relative?

The discussion has advanced regarding wearing a necktie and wearing it if it is made of silk or mixed with it. If the necktie is made of natural silk, it is not permissible to gift it to men for them to wear, because that is considered assisting in the forbidden, in accordance with the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
