Question: Who was the first to link hashish to the members of the “Hashish Brotherhood” (the Hashishin/Assassins)?

Explanation: The lectures credit Silvestre de Sacy with making the philological argument that connected the term Hashishin/Hashishiyyin to hashish in European scholarship, helping cement the association in modern European writing. (Lecture/Reading: Guba de Sacy, “de Sacy and the myth of the Hashishin”.)
