Almighty Allah recounted: And recite to them the story of Abraham. When he said to his father and his people: "What do you worship?" They said: "We worship idols, and to them we are ever devoted." He said: "Do they hear you, when you call (on them)? Or do they benefit you or do they harm (you)?" They said: "Nay, but we found our fathers doing so."

He said: "Do you observe that which you been worshipping, - You and your ancient fathers? - Verily! They are enemies to me, save the Lord of the Alamin (mankind, jinn, and all that exists); Who has created me, and it is He Who guides me; and it is He Who feeds me and gives me to drink. And when I am ill, it is He who cures me; and Who will cause me to die and then will bring me to life (again); and Who, I hope will forgive me my faults on the Day of Recompense, (the Day of Resurrection)." Surah 26: 69-82

In another surah The Almighty revealed: And (remember) Abraham when he said to his people: "Worship Allah (Alone), and fear Him, that is better for you if you did but know. You worship besides Allah only idols, and you only invent falsehood. Verily, those whom you worship besides Allah have no power to give you provision, so seek your provision from Allah (Alone), and worship Him (Alone), and be grateful to Him. To Him (Alone) you will be brought back. And if you deny, then nations before you have denied (their Messengers). And the duty of the Messenger is only to convey (the Message) plainly."

Say: "Travel in the land and see how (Allah) originated creation, and then Allah will bring forth (resurrect) the creation of the Hereafter (i.e., resurrection after death). Verily, Allah is Able to do all things."

He punishes whom He wills, and shows mercy to whom He wills, and to Him you will be returned. And you cannot escape in the earth or in the heaven. And besides Allah you have neither any Wali (Protector or Guardian) nor any Helper. And those who disbelieve in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah and the Meeting with Him, - it is they who have no hope of My Mercy, and it is they who will have a painful torment.

Abraham Breaks the Idols
He explained to them the beauty of Allah's creation, His power and wisdom. Idol worship is detested by Allah, for Allah is the Lord of the universe Who created mankind, guided him, provided him with food and drink, and cured him when he was sick, and Who will cause him to die and be raised up again. It was He to Whom Abraham prayed and Who would forgive his sins on the Day of Judgment. However, they would not give up but clung fast to idolatry.
Abraham left his father's house and abandoned his people and what they worshipped. He decided to do something about their state of disbelief, but did not reveal it. He knew that there was going to be a great celebration on the other bank of the river which would be attended by all the people. Abraham waited until the city was empty, then came out cautiously, directing his steps towards the temple. The streets leading to it were empty and the temple itself was deserted, for the priests had also gone to the festival outside the city.
Abraham went there carrying a sharp ax. He looked at the stone and wood statues of the gods and at the food laid in front of them as offerings. He approached one of the statues and asked: The food in front of you is getting cold. Why don't you eat?" The statue kept silent and rigid. Abraham asked the other statues around him: "Will you not eat (of the offering before you)?" Surah 37: 91
He was mocking them for he knew they would not eat. He once again asked then: "What is the matter with you that you do speak not?" Surah 37: 92
He then raised his ax and started smashing the false gods worshipped by the people. He destroyed them all except one, on whose neck he hung the ax. After this his anger subsided and he felt at peace. He left the temple. He had fulfilled his vow to show his people a practical proof of their foolishness in worshipping something other than Allah.
