Isaac/ Ishaq:-                

       The only son from Sarah and the one who was to have been offered for sacrifice in the Torah

Genesis Chapter 22
1.        And it came to pass after these things, that God tested Abraham, and said to him, Abraham; and he said, Behold, here I am.2. And he said, Take now your son, your only son Isaac, whom you love, and go to the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell you.

3.        And Abraham rose up early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son, and broke the wood for the burnt offering, and rose up, and went to the place of which God had told him.4. Then on the third day Abraham lifted up his eyes, and saw the place far away.5. And Abraham said to his young men, Stay here with the ass; and I and the lad will go yonder and worship, and come back to you.

6.        And Abraham took the wood of the burnt offering, and laid it upon Isaac his son; and he took the fire in his hand, and a knife; and they went both of them together.

7.        And Isaac spoke to Abraham his father, and said, My father; and he said, Here am I, my son. And he said, Behold the fire and the wood; but where is the lamb for a burnt offering?8. And Abraham said, My son, God will provide himself a lamb for a burnt offering; so they went both of them together.9. And they came to the place which God had told him; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood.

10.        And Abraham stretched out his hand, and took the knife to slay his son.11. And the angel of the Lord called to him from heaven, and said, Abraham, Abraham; and he said, Here am I.12. And he said, Lay not your hand upon the lad, nor do anything to him; for now I know that you fear God, seeing that you did not withhold your son, your only son from me.

13.        And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns; and Abraham went and took the ram, and offered him up for a burnt offering in place of his son.14. And Abraham called the name of that place Adonai-Yireh; as it is said to this day, In the Mount of the Lord it shall be seen.15. And the angel of the Lord called to Abraham from heaven the second time,

16.        And said, By myself have I sworn, said the Lord, for because you have done this thing, and have not withheld your son, your only son;17. That in blessing I will bless you, and in multiplying I will multiply your seed as the stars of the heaven, and as the sand which is upon the sea shore; and your seed shall possess the gate of his enemies;18. And in your seed shall all the nations of the earth be blessed; because you have obeyed my voice.

         The version in the Quran is completely incompatible and different (S37:100/107) from the Biblical narrative. None the less, the Quran does not assert or allege that it was Ishmael who was being offered for a sacrifice, as the later Muhammadan scholars in desperation, concocted as an alternative story.

       The Biblical verses above show repeatedly and with great precision that it  is always Isaac, and ONLY Isaac, who is considered as Abraham's foremost son, as in the repeated description of
                               "your son, your ONLY son ".

       More over, Isaac's name appears in association with Ishmael in the following four Suras (2:133&136&140; 3:84; 4:163; 14:39).

       His name appears alone (without Ishmael) in association with Abraham or Jacob in the following eight Surahs (6:84; 11:71; 12:6; 38; 19:49; 21:72; 29:27; 37:112 & 113; 38:45).

        The Quran mentions Isaac's name on Sixteen occasions while that of Ishmael only Eight times.

       *** It is a great insult to the human intellect, as well as a pitiable  and pitiful endeavour that the followers of Muhammad attempt their best to PERVERT, CONTORT and TWIST, Recorded History, Facts, Reality and Language in order to give themselves a WORTHY ANCESTRY, at any cost ***
