Terah or Térach (Hebrew: תֶּרַח / תָּרַח, Modern Téraḥ / Táraḥ Tiberian Téraḥ / Tāraḥ ; "Ibex, wild goat", or "Wanderer; loiterer") is a biblical figure in the Book of Genesis, son of Nahor, son of Serug and father of the Patriarch Abraham, all descendants of Shem's son Arpachshad. Terah is mentioned in the Hebrew Bible  and in the New Testament.
Most of what is told about Terah is recorded in Genesis 11:26–28. Terah's father was Nahor, son of Serug, descendants of Shem.[v.10] They and many of their ancestors were polytheistic. Regarding his children, Terah had three sons: Abram (better known by his later name Abraham), Haran, and Nahor II.[v.26] His daughter Sarai, by a second wife, was also his daughter-in-law, wife of Abram. The entire family, including grandchildren, lived in Ur of the Chaldees.[v.31] One of his grandchildren was Lot, whose father, Haran, had died before the family left Ur.[v.28] Terah's son Abram had an encounter with God, who directed him to take the entire family, leave Ur, and move to the land of Canaan. Terah coordinated the journey, intending to go to this new land, but stopped in the city of Haran[v.31] along the way, where he died at the age of 205.[v.32]

In his final speech to the Israelite leaders assembled at Shechem, Joshua recounts the history of God's formation of the Israelite nation, beginning with "Terah the father of Abraham and Nahor, [who] lived beyond the Euphrates River and worshiped other gods" (Joshua 24:2).
Genesis 11:26 states that Terah lived 70 years, and he begat Abram, Nachor, and Haran. Rashi  comments on the subsequent elaboration on the story of Abraham that Abraham was the gem of the chronology of Genesis 11 which the Torah wanted to focus on. In the Jewish tradition, Genesis (11:26) teaches that Terah was 70 years old when he begat Abram. The Talmud  says that Abraham was 52 years old at year 2000 AM (Anno Mundi), which means that he was born in the year 1948 AM. Rashi  explains this based on Abram being born when Terah was 70. While it is a given in Jewish tradition that Genesis (11:26) relates that Abram was born when Terach was 70, which is the basis of the current Jewish year, there is yet a question whether Abram was born first as listed, or perhaps last, and is listed first as the wisest similar to Shem, Ham, and Jafeth where Shem was the youngest but wisest. Seder Olam Rabbah holds that Abram was the eldest, but the Talmud  leaves the above question open.
According to rabbinical tradition Terah was a wicked (Numbers Rabbah 19:1; 19:33), idolatrous priest (Midrash HaGadol on Genesis 11:28) who manufactured idols (Eliyahu Rabbah 6, and Eliyahu Zuta 25). Abram, in opposition to his father’s idol shop, smashed his father’s idols and chased customers away. Terah then brought his unruly son before Nimrod, who threw him into a fiery furnace, yet Abram miraculously escaped.(Genesis Rabba 38:13). The Zohar says that when God saved Abram from the furnace, Terah repented (Zohar Genesis 1:77b) and Rabbi Abba B. Kahana said that God assured Abram that his father Terah had a portion in the World to Come (Genesis Rabbah 30:4; 30:12).
Terah is identified as the person who arranged and led the family to embark on a mysterious journey to Canaan. It is shrouded in mystery to Jewish scholars as to why Terah began the journey and as to why the journey ended prematurely. It is suggested that he was a man in search of a greater truth that could possibly be found in the familiar land of Canaan, and that it was Abram who picked up the torch to continue his father's quest, that Terah himself was unable to achieve. 
In Jewish tradition Abram left Haran before Terah died as an expression that he would not be remiss in the Mitzvah, of honoring a parent, by leaving his aging father behind. The significance of Terah not reaching Canaan, was a reflection of his character, a man who was unable to go “all the way”. Though on a journey in the right direction, Terah fell short at arriving to the divine destination — in contrast to Abram, who did follow through and achieved the divine goal, and was not bound by his father’s idolatrous past. Abram's following God’s command to leave his father, thus absolved him from the Mitzvah of honoring parents, and as Abraham, he would go on to create a new lineage distinct from his ancestors. However, in Christian tradition Abram left Haran after Terah died, see below.
The Christian views of the time of Terah come from a passage in the New Testament at Acts 7:2–4 where Stephen said some things that contrast with Jewish Rabbinical views. He said that God appeared to Abraham in Mesopotamia, and directed him to leave the Chaldeans—whereas most Rabbinical commentators see Terah as being the one who directed the family to leave Ur Kasdim from Genesis 11:31: "Terah took his son Abram, his daughter-in-law Sarai (his son Abram's wife), and his grandson Lot (his son Haran's child) and left Ur of the Chaldeans to go to the land of Canaan." Stephen asserts that Abram left Haran after Terah died.
In some Islam sects, Abraham's father is believed to have been an ignorant man, who refused to listen to the constant advice of his wise son. In fact, the earliest story involving Abraham in the Qur'an is his discussion with his father. The name given for this man in the Qur'an  is Āzar (Arabic: ءازَرُ), though Arab genealogists related the name of Abraham's father as Tāraḥ (Arabic: تَارَح).
Shia Muslims believe that the father Azar mentioned in Quran was Abraham's uncle, not his biological father, as it is used to call the uncle as father. We can see that in Quran when the 12 apostles promised their father Jacob on his death time that they will worship the God of their fathers Isaac and Ishmael and Ibrahim, and Ishmael is their uncle not their father but still they named him amongst their fathers.
As a father, Azar required his son's most sincere advice. Abraham, after receiving his first revelations from God, invited his father to the way of Islam. Abraham explained to him the faults in idolatry, and why he was wrong to worship objects which could neither hear nor see. From the Quran 74/6 "And [mention, O Muhammad], when Abraham said to his father Azar: Do you take idols as deities? Indeed, I see you and your people to be in manifest error." Abraham told his father that he had indeed received revelations from God, knowledge which his father did not possess, and told him that belief in God would grant him immense rewards in both this life and the hereafter. Abraham concluded his preaching by warning Azar of the grave punishment he would face if he did not mend his ways. When Abraham offered his father the guidance and advice of God, he rejected it, and threatened to stone him to death. Abraham prayed for his father  to be forgiven by God, and although he continued to seek forgiveness, it was only because of a promise that he had made earlier to him. When it became clear that Azar's unrelenting hatred towards pure monotheism would never be fought, Abraham dissociated himself from him.
The Qur'an states that the people of Abraham were idolaters. When Abraham had become forty, he decided to finally teach his community a lesson. He said to himself that he had a plan for their idols, whilst they would be gone away. The Qur'an goes on to narrate that Abraham subsequently broke the idols, all except the largest, which he kept intact. When the people returned, they began questioning each other over the wreckage, until some of the people remembered that the youth, Abraham, had spoken of the idols earlier. When Abraham arrived, the people immediately began to question him, asking him whether he had anything to do with the broken idols. Abraham then, in a clever taunt, asked the people as to why they do not ask the largest of the idols, which, they believed, could indeed hear and speak. The people of Abraham were then confounded with shame, and admitted that the idols were incapable of anything.
After the incident of the idol wreckage, the people of Abraham, while having admitted their fault, are said to have ignored Abraham's warning and instead retaliated by throwing him into a fire and exclaiming "protect your gods". Although the natural nature of fire is one of intense heat, God commanded the flame to be cool and peaceful for Abraham. Abraham, as a result, remained unhurt both physically and spiritually, having survived the fire of persecution. The people continued to taunt and persecute him, but to no avail, as the Qur'an says that it was they "that lost most".
