Without deciding the issue of the location of the Ur of the Chaldeans of Genesis 11:28 and 31 (also Genesis 15:7 and Nehemiah 9:7), we understand from the Old Testament that Abraham lived for a time at Haran about 25 miles south of Şanliurfa in southeastern Anatolia (modern Turkey).
Local Muslim tradition in Urfa claims that Abraham was born in a cave in the city, and legend says he was hidden by his mother in the cave for 15 months.
In the first photograph you see the Mosque associated with the cave of Abraham and the Citadel (Kale) which is thought to date to the Hellenistic period.
To the left of the courtyard is an entrance to the cave in which it is claimed that Abraham was born.
Men and women have separate entrances to the cave.
There appears to be a spring in the cave. Men are able to see further into the cave and have the opportunity to drink from the water using one of the cups that are provided. I do not know about the arrangement for the women.
A sign at the cave explains the tradition. It seems not to have been written by native English speakers, but I think you will be able to make out the meaning.
Here is my copy of the sign without corrections.
Mevlid means “holly nativity/birth”. It’s believed that Abraham was born in this cave, there fore it is named as Mevlid-i Halil Cave. According to the legend, when the oracles of King Nimrud told him that there would be born a son who would destroy and end his dynasty and his religion, Nimrud ordered that all the sons would be born that year should be killed strictly. Within the year, Nuna, who was the mother of Abraham, noticed that she was pregnant. For a while she hid her pregnancy. When the date of birth arrived, she sheltered in this cave and gave birth to Abraham inside here. After the birth, she came here every day secretly and nursed her son. Meanwhile according to the legend, it’s believed that Abraham was also miracally nursed by a gazelle by the order of God and within the 15 months he passed in the cave, it’s believed that he grew up to the age of 15.
I understand the last sentence to say that Abraham grew to age 15 in just 15 months! The legend seems to mix a bit of the story of the birth and infancy of Moses who was hidden among the reeds along the Nile River for three months by his parents (Exodus 2:2-4; Hebrews 11:23) with the murder of the innocents by the hands of Herod the Great in an attempt to kill the infant Jesus (Matthew 2:16).
Like Christians and Jews, Muslims have a multitude of traditions and legends that have grown up around Biblical and Quranic characters.
