Abu ʾl-Fatḥ Naṣr Allāh ibn ʿAbd Allāh (Arabic: ابن قلاقس الإسكندري; 1137–1172), known as Ibn Qalāqis (or Ḳalāḳis) and also al-Qāḍī al-aʿazz ("he most honorable judge"), was an Egyptian Arab poet and author. He spent his last few years travelling widely through Sicily and Yemen. The collections of poems and letters he left behind contain much valuable information for historians. Source: Wikipedia (en)
