Within the grand Dergah Complex is the Hazreti Ibrahim Halilullah, the cave where the Prophet Abraham is said to have been born.
Local legend says that the prophet's mother gave birth to him here in secret because King Nimrod had been warned in a prophesy that a great leader would soon be born and so set out to kill all of Ur's newborns.
Just to the west, across a central courtyard, is the regal facade of the Mevlid-i Halil Mosque.
