"When Isaac was grown, someone appeared to Abraham in a dream and said to him: "Keep your vow which you made! God bestowed upon you a boy by Sarah so that you may sacrifice him" So he said to Isaac: "Let us go offer a sacrifice to God!" So he tool a knife and some rope and went with him until they reached a place in the mountains. The boy said to him: "Oh father! Where is your sacrifice?" He replied: "Oh my son, I saw in a dream, that I will slaughter you. So pay attention to what you see". He said "Oh my father, do what you have been commanded; you will find me, if God wills, one of the patient". Isaac then said to him: "Make tight my bonds, so that I will not struggle to pull back your clothes so that none of my blood will be shed on them for Sarah will see it and be grieved. Hurry! Pass the knife over my throat so that death will be easy for me. When you come to Sarah, greet her'. Abraham began to approach him and, while crying, tied him up. Isaac too was crying such that the tears gathered by cheek of Isaac. He then drew the knife along his throat but the knife did not cut, for God had placed a sheet of copper on the throat of Isaac. When he saw that, he turned him on his forehead and nicked him on the back of the head just as God has said in Quran 37:103: When they had both submitted and he flung on his forehead, that is they had submitted the affair to God. A voice called out: 'Abraham, you have fulfilled the vision!" He turned around and behold, there was a ram. He took it and released his son and he bent over his son saying: "Oh my son, today you have been given to me". That comes in God's saying in Quran 37:107: We ransomed him with a great sacrifice."
