Lisan ad-Din ibn al-Khatib (Arabic: لسان الدين ابن الخطيب) (Born 16 November 1313, Loja– died 1374, Fes, Morocco) (Full name Muhammad ibn Abd Allah ibn Said ibn Ali ibn Ahmad al-Salmani) (محمد بن عبد الله بن سعيد بن عبد الله بن سعيد بن علي بن أحمدالسّلماني) was an ArabAndalusian polymathpoet, writer, historian, philosopher, physician and politician from Emirate of Granada. Some of his poems decorate the walls of the palace of Alhambra in Granada.
Al-Khatib was born at Loja, near Granada. For much of his life he was vizir at the court of the Sultan of Granada, Muhammed V. He spent two periods in exile in the Marinid empire in Morocco; (between 1360-62, and 1371-74, he resided variously at Ceuta, Tlemcen and Fes). In 1374, he was imprisoned for 'Zandaqa' (heresy) and atheism. He was sentenced to death by suffocation. Earlier and modern historians have speculated that his many private and political feuds in Granada with the Nasrid Kings of Granada, were probably the main factors in his treatment and execution. His body was burned before being buried at "Bab Mahruq", a city gate in Fes.
