Across the world, الدين (الدين 
, Eddine 
, Eddin ) is quite a common unisex first name. The given name الدين is habitual in Northern Africa, particularly Algeria, where it is quite a rare principally masculine, but scarcely feminine name, Sudan, where it is quite a rare male name, and Libya, where it is quite a rare epicene name. Not in comparison with a country's population, it is the most numerous in Northern Africa, particularly Egypt, Algeria, and Sudan. Much more frequently, الدين is the last name as well as the forename.
