Abu Muhammad ‘Abdallah ibn Muhammad ibn Hajjaj ibn al-Yasmin al-Adrini al-Ishbili;
(died 1204) more commonly known as ibn al-Yasmin, was Berber mathematician. His place of birth is unknown, but he received his education in Sevilla, Spain. Little is known of his personal life, except that he was born into a Berber family and according to Ibn Sa’id, he was black like his mother. Since some historians have given him the surname al-Ishbili, he may have been born or grown up in Seville. Beside mathematics, he also became famous in literature, law, and particularly in Andalusian poetry.
