Muḥammad Bey Abū aḏ-Ḏahab (1735–1775), also just called Abū Ḏahab (meaning "father of gold", a name apparently given to him on account of his generosity and wealth), was a Mamluk emir and regent of Ottoman Egypt. Born in the North Caucasus region of Circassia or in Abkhazia he was kidnapped and sold to the Mamluk Emir Ali Bey al-Kabir in Egypt. He became Ali Bey's closest and favourite fellow, his most trusted general and even his brother-in-law (according to other sources: son-in-law or adoptive son).
