Abu al-ʿAbbās Abd Allāh ibn Muḥammad ibn ʿAlī ibn ʿAbd Allāh ibn ʿal-ʿAbbās (Arabic: أبو العباس عبد الله ابن محمد ابن علي, romanized: Abū al-ʿAbbās ʿAbd Allāh ibn Muḥammad ibn ʿAlī‎; 721/722 – 8 June 754),^[1] known by his laqab al-Saffah (Arabic: السفّاح, romanized: al-Saffāḥ), was the first caliph of the Abbasid Caliphate, one of the longest and most important caliphates in Islamic history.

His laqab al-Saffāḥ (السفّاح) means "the Blood-Shedder". It may refer to his ruthless tactics, or perhaps it was used to intimidate his enemies, as it was common in history to adopt such names, an example for this is “Al Abbas” which means a “Lion that scares away other animals”.
