Prophet Ibrahim AHS (PBUH) was intended to be burnt to death in a very-very large fire at the spot behind the photographer of the photograph below. The two pillar/posts seen on this photograph were thought to be used to catapult the Prophet from high up the hillside to a spot at the foot of the hill, where the fire was burning furiously. The distance between the fire and the catapult gives some idea on how hot the fire was.
The site where the fire was situated was also the site of the cave, where the Prophet was born. There is a claim that Prophet Ibrahim was born in Ur, which is situated in Southern Iraq. Both claims are plausible, since they are situated within the Sumerian and Babylonian empires. The claim that Ur is the more plausible one stood until the discoveries of very early civilizations that were uncovered from excavations done in areas near Urfa. The civilizations were dated back as far as 11,500 BC. For more information check at this URL: http://www.bibliotecapleyades.net/arqueologia/gobekli_tepe05.htm
The episode of burning is recorded in the Al-Quran Al-Karim in Surah Al-Ambia (Surah 21) as folllows:
Translation of Al-Quran by Sahih International
When he said to his father and his people, "What are these statues to which you are devoted?"
They said, "We found our fathers worshippers of them."
He said, "You were certainly, you and your fathers, in manifest error."
They said, "Have you come to us with truth, or are you of those who jest?"
He said, "[No], rather, your Lord is the Lord of the heavens and the earth who created them, and I, to that, am of those who testify.
And [I swear] by Allah , I will surely plan against your idols after you have turned and gone away."
So he made them into fragments, except a large one among them, that they might return to it [and question].
Al-Ambiya 21: 59
They said, "Who has done this to our gods? Indeed, he is of the wrongdoers."
They said, "We heard a young man mention them who is called Abraham."
They said, "Then bring him before the eyes of the people that they may testify."
They said, "Have you done this to our gods, O Abraham?"
He said, "Rather, this - the largest of them - did it, so ask them, if they should [be able to] speak."
So they returned to [blaming] themselves and said [to each other], "Indeed, you are the wrongdoers."
Then they reversed themselves, [saying], "You have already known that these do not speak!"
He said, "Then do you worship instead of Allah that which does not benefit you at all or harm you?
Uff to you and to what you worship instead of Allah . Then will you not use reason?"
They said, "Burn him and support your gods - if you are to act."
Allah said, "O fire, be coolness and safety upon Abraham."
And they intended for him harm, but We made them the greatest losers.
From these verses Allah tells us that Abrahim had destroyed all the idols in a temple, except the largest one. He left the axe that he had used to fragment the idols beside the largest idol. When he was caught and brought to the temple, he was questioned as to whether he was the person who had destroyed the idols. In reply he told the people to ask the largest idol if it could tell them what it saw. The people were so angry that they reported the incidence to King Nimrod, who then ordered for the burning of Prophet Ibrahim. But when the Prophet was in the fire, he was not burned, instead he was feeling the coolness of fire.
When Allah wants something it will happen, even though it is against the normal rule of life. When Allah wants thing to happen the way He wants, He commands "Be" and the thing happens. He can create anything he wants:
Surah Yasin 36:81
"Is not He who created the heavens and the earth able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator."
Surah Yasin 36:82
His command is only when He intends a thing that He says to it, "Be," and it is.
Including if there in no father and mother:
Surah Ali Imran 3:59
"Indeed, the example of Jesus to Allah is like that of Adam. He created him from dust; then He said to him, "Be," and he was.""
