A: Wearing the turban is established from the Sunnah. Similarly it is established in certain Ahaadith that Hazrat Rasulullah (Sallallahu Alayhi Wasallam) tied the turban for certain Sahaabah. In our urf (usage) at the time Ulama' qualify, then senior Ulama' tie turbans on their heads before the public as a sign of acknowledgment and recognition of the capability of these graduates.
