The Fidai were some of the most feared assassins in the then known world. Sinan ordered assassinations against politicians and generals such as the great Kurdish general and founder of the Ayyubid dynasty, Saladin. A sleeping Saladin had a note from Sinan delivered to him by a Fidai planted in his entourage. The note was pinned to his pillow with a dagger, and it informed Saladin that he had been spared this once and should give up his anti-Nizari militancy. A shaken Saladin quickly made a truce with Sinan.
