Thanks for the info, I had no idea. I will avoid hash as well.
They were famous for stabbing their victims right during religious worship right in the middle of the Mosque on a Friday (their sabbath). It was, obviously, a suicide mission.
When Saladin took a hard line against the cult - they promised to make him think better of it. Saladin put men positioned outside his tent in a ring with interlocking arms - but he STILL woke up with a red dagger (their symbol) stuck in the sand beside his head. He remarked “they have arguments that are difficult to dismiss.”
The name “Assassin” is actually derived from the Hashish they used to smoke.
