No, Abraham by faith obeyed the call to go to the land where he would receive his inheritance (Hebrews 11:8).
In Matthew 4:15-23, Jesus began his ministry with the Gospel message to repent for the Kingdom of God is at hand, which was a light to the Gentiles, and the Law of God was how his audience knew what sin is (Romans 3:20), so repenting from our disobedience to it a central part of the Gospel message, which was in accordance him being sent as the promised seed to bless us by turning us from our wickedness (Acts 3:25-26), which was the Gospel that made known in advance to Abraham in accordance with the promise (Galatians 3:8), which he spread to those in Haran in accordance with the promise (Genesis 12:1-5), and which he spread to his children and those of his household in accordance with the promise (Genesis 18:19). So Abraham believed the promise since his introduction in Genesis 12 and actively worked in order to bring it about.
If you are interested, then there are traditions within Judaism about how Abraham turned from idolatry.
Joshua 24:2
"And Joshua said unto all the people, Thus saith the LORD God of Israel, Your fathers dwelt on the other side of the flood in old time,
even Terah, the father of Abraham, and the father of Nachor: and they served other gods."
What Joshua writes MAY give some indication that Abraham MIGHT have been involved in idolatry, but it does not specifically say he was. Many commentators think otherwise:
Barnes:
"It is not stated that Abraham himself was an idolater, though his fathers were. Jewish tradition asserts that Abraham while in Ur of the Chaldees was persecuted for his abhorrence of idolatry, and hence, was called away by God from his native land. "
Coffman:
"Both Terah (Abraham's father) and Nahor, his uncle, were idolaters, but it is NOT stated that Abraham was an idolater. There is no reason to doubt the Jewish tradition that, "Abraham, while in Ur of the Chaldees was persecuted for his abhorrence of idolatry, and hence, was called away by God from his native land."(F19)"
Joseph Exell
"The Rabbinic tradition has great probability in it, that Abraham was driven out of his native country for refusing to worship idols. It is difficult to understand his call otherwise. No doubt his great and pure soul had learned to abhor the idolatrous and cruel worship of his countrymen. By inward struggles, perhaps by the vague survival of the simpler and truer faith which has been held to underlie every polytheistic system, he had "reached a purer air," and learned to adore the One True God. His family were led to embrace his doctrines, and they left their native land with him. But Haran, with its star worship, was no resting place for him."
Other think he was an idolator:
Adam Clarke:
" Probably Abraham as well as Terah his father was an idolater, till he received the call of God to leave that land. "
