Thia is the Arabic word for grass or hay.

Hashish or marijuana is often referred to as “grass” as a slang term, but the Arabic word is used as a generic botanical term as well as referring to the narcotic.

The word gave its name to the medieval military group known as the Assassins who, at least according to the populist reports of the time, were drugged and then given a taste of the Islamic paradise described in the holy Quran.

The story goes, once they has glimpsed the beautiful gardens and rivers running with wine, and beautiful women escorts who are always described as wide-eyed houris, they wanted more. And then more.

Entranced in this way, they would do almost anything required of them as soldiers to their military leader.

Hence they became Assassins, ready to go undercover whenever required and taking on the most dangerous military operations.
