Site where Ibrahim (a.s.) was thrown into the fire
This site in Urfa, Turkey is believed to be the place where Ibrahim (a.s.) was thrown into the fire by Namrud (Nimrod) for refusing to submit to the worshipping of idols. Close by is a cave where he is said to have been born. Urfa was formerly known as Edessa and was the setting for several battles during the Crusades.
Note that this incident and the birth of Ibrahim (a.s.) is also claimed to be in Ur, in southern Iraq.
