Khayr al-Din ibn Ahmad ibn Nur al-Din Ali ibn Zayn al-Din ibn Abd al-Wahab al-Ayubi al-Farooqui (1585–1671), better known as Khayr al-Din al-Ramli (Arabic: خير الدين الرملي), was a 17th-century Islamic jurist, teacher and writer in then Ottoman-ruled Palestine. He is well known for issuing a collection of fatwas that became highly influential in Hanafi (one of four major schools of thought in Sunni Islam) jurisprudence in the 18th and 19th centuries.
