Cold Fire!
People worship idols, the moon, the sun and the stars -  - Image © Play & Learn In the town where Prophet Ibrahim (pbuh) lived, people worship idols, the moon, the sun and the stars.

Prophet Ibrahim always told them to worship and one and only Allah and not these false Allahs.

On the day of the festival, when all the people, young and old, had left the town, Prophet Ibrahim was alone. He went to the main temple where all the important idols were kept. He took an axe and broke all the idols except the largest one. The idols, which had been kept neat and tidy, now lay in pieces on the ground. Before he left the temple, Prophet Ibrahim put the axe in the hands of the largest, unbroken, idol. People would not listen to him. So one day when all the people had gone out of town to celebrate a festival, Prophet Ibrahim (pbuh) went to the main temple where all the important idols were kept. He took an axe and broke all the idols except the largest one. The idols, which had been kept neat and tidy, now lay in pieces on the ground. Before he left the temple, Prophet Ibrahim put the axe in the hands of the largest, unbroken, idol.

When they returned and found what had happened to their God's, they were shocked and said, "Who has done this cruel thing to our lords?" One of them said, "It must be Ibrahim (pbuh). He has always hated idol worship."

Prophet Ibrahim was brought to court. When Prophet Ibrahim (pbuh) was asked if had broken the idols he replied, "It must have been done by the biggest idol. Ask him about it." But the people said, "Our idols do not talk or answer questions." He said, "Shame on you! How can you worship pieces of wood and stone. They do not know anything and can neither harm nor benefit you." However, nobody was willing to listen to his words and he was declared guilty. The people began to shout, "Burn him alive! Let him be with his Lord."

A big bonfire was built and Prophet Ibrahim (pbuh) was thrown into it. Allah told the fire.
"...O fire be cold and safe from Ibrahim" (Quran 21:69)
