The Biblical Abraham

Abraham is honoured by all three monotheist religions in the world: Judaism, Christianity and Islam. He was the common ancestor, so to speak. Therefore, it is profitable to know about his story in Genesis. I hope someone will enlighten me on how the Koran presents his story. His story began at the last few verses of Genesis 11, which lay down the background of Abraham.
Shem was one of the three sons of Noah. Among his descendants, there was a Terah who lived in Ur of Chaldeans.
When Terah had lived seventy years, he became the father of Abram, Nahor, and Haran (Genesis 11:26).
From this reading, Abram seemed to be the first born of Terah. The children of Haran were Lot, Milcah and Iscah. Haran died before Terah.
Abram told a wife called Sarai and Nahor took Milcah, his niece as his wife (Genesis 11:29).
According to another tradition, Sarai was the sister of Abram, the daughter of Terah, but not the daughter of the mother of Abram (Genesis 20:12). Then the story continues with Terah moving to Canaan.
Terah took Abram his son and Lot the son of Haran, his grandson, and Sarai his daughter-in-law כַּלָּתוֹ , his son Abram's wife, and they went forth together from Ur of the Chaldeans to go into the land of Canaan; but when they came to Haran, they settled there (Genesis 11:31).
Haran, the city, not the son of Terah, was probably a fertile place and Terah did not continue his journey. Had he continued, Terah, instead of Abraham, would have been the Patriarch of the salvation history. Of course, God had not chosen Terah for some unknown reasons. Probably he was not adventurous enough to explore new ground. He was probably forced to leave Ur and settled himself at the first place of comfort. The mission to inherit Canaan was left to Abram to accomplish.
They must have stayed in Haran for a long time for it to be called Abram's country. One day, God called Abram who was then 75.
Now the LORD said to Abram, "Go from your country and your kindred and your father's house to the land that I will show you.
And I will make of you a great nation, and I will bless you, and make your name great, so that you will be a blessing.
I will bless those who bless you, and him who curses you I will curse; and by you all the families of the earth shall bless themselves." (Genesis 12:1-3)
Throughout the salvation history, God always takes the initiative. He takes the initiative to search for the appropriate candidates. When He has found one, He would revealed Himself and made promises. Was the other party required to perform any obligation in return? Yes, when the situation arose such as God's demand of the sacrifice of Isaac some thirty two years later. Some centuries later, the relationship between God and His people was formalized in the form of the Sinai Covenant.
Abram took Sarai and Lot along, passing through Shechem, Bethel and moving towards Negeb. There was a severe famine in the region and they moved into Egypt (Genesis 12:10). One of the three wife-sister narratives in Genesis then took place. The honesty of Abram was called into question.
When he was about to enter Egypt, he said to Sarai his wife, "I know that you are a woman beautiful to behold;
and when the Egyptians see you, they will say, 'This is his wife'; then they will kill me, but they will let you live.
Say you are my sister, that it may go well with me because of you, and that my life may be spared on your account." (Genesis 12:11-13)
Pharaoh took Sarai and gave Abram a lot of cattle. Consequently, God afflicted the house of Pharaoh with great plagues. So, Pharaoh returned Sarai to Abram and sent them away. Abram left Egypt richer (Genesis 12:16-20).
On the surface, Abram had cheated Pharaoh in order to save his own life. If we apply the Kantian Categorical Imperative to analyze this case, Abram had told a lie. It was unethical. I discussed with my son Wulstan. He said we could look at the incident from another angle. Abram took an action to prevent the Egyptians from committing murder. This case is similar to Abigail's attempt to prevent David from killing her husband Nabal (1 Samuel 25:24-26). Therefore, Abram was not unethical. This is a good piece of argument. I still have a lot to learn from my son.
Moreover, we understand very little about ancient customs in the Near East. It was possible that a wife took on the status of a daughter. That probably explains why the wife of a son is called the daughter-in-law in relation to the parents. Therefore, an ethical analysis must take into consideration a wide range of knowledge. It is really challenging. Abram's integrity remains untarnished.

Dear Lord, I praise You for Your wisdom. I humble myself in front of You. Grant me the wisdom to lead a faithful life. Amen.
