Muhammad ibn Zakariya al-Razi
The earliest mention of coffee noted by the literary coffee merchant Philippe Sylvestre Dufour is a reference to "bunchum" in the works of the 10th century CE Persian physician Muhammad ibn Zakariya al-Razi, known as Rhazes in the West, but more definite information on the preparation of a beverage from the roasted coffee berries dates from several centuries later. One of the most important of the early writers on coffee was Abd al-Qadir al-Jaziri, who in 1587 compiled a work tracing the history and legal controversies of coffee entitled "Umdat al Safwa fi hill al-qahwa" عمدة الصفوة في حل القهوة. He reported that one Sheikh, Jamal-al-Din al-Dhabhani (d. 1470), mufti of Aden, was the first to adopt the use of coffee (circa 1454).
