Story about muslims with a happy ending(muslims all get slaughtered) i.e. the tale of the idiot who seized a Mongolian trade caraven, took everything, killed everybody, and when Genghis Khan sent four ambassadors to figure out what the **** had happened, burned their beards off and sent them back like that to show Genghis Khan how bad he was...
The first incident was the governor of Otar, in the northeast of the Khwaresm Empire. The killing of the ambassadors was the stupidity of his boss, Mohammed Ali, the Khwaresm Shah. The result was the destruction of Khwaresm, the annihilation of most of an army reported to number 500,000.
