Question: where does the last name coffee come from

title: Coffee
text: Other accounts attribute the discovery of coffee to Sheikh Omar . According to an ancient chronicle ( preserved in the Abd - Al - Kadir manuscript ) , Omar , who was known for his ability to cure the sick through prayer , was once exiled from Mocha in Yemen to a desert cave near Ousab ( modern day Wusab , about 90 km east of Zabid ) . Starving , Omar chewed berries from nearby shrubbery , but found them to be bitter . He tried roasting the seeds to improve the flavor , but they became hard . He then tried boiling them to soften the seed , which resulted in a fragrant brown liquid . Upon drinking the liquid Omar was revitalized and sustained for days . As stories of this `` miracle drug '' reached Mocha , Omar was asked to return and was made a saint . From Ethiopia , the coffee plant was introduced into the Arab World through Egypt and Yemen .
