What is the ruling of Islamic scholars regarding wearing a tie made of pure silk or silk mixed with other materials? If permissible, what is the acceptable amount of silk to be used in the tie?
Bismihi ta'ala
Wearing of pure silk is haram for men. If it is mixed with silk, then it would be permissible., which means it is not 100% silk. As a neck-tie is considered "wearing", then it would be haram if it is pure silk.
And Allah knows best
