El Hashashin.

Inspired by true history, The Assassins chronicles the rise of Hassan al-Sabbah in 11th-century Persia — the enigmatic founder of the Order of Assassins, who forged a cult of absolute loyalty and terrorised rulers across the Islamic world. Starring Karim Abdel Aziz, the series weaves together politics, faith, betrayal and bloodshed in one of the most visually ambitious and widely debated productions in Arab television history.
