@Harunshehu - sincere thanks for having an intelligent discussion about the scriptures with issues concerning Ishmael and Isaac. You did add on your own that Ishmael was the son of the promise, I will have to disagree because the Holy Scripture did not accord Ishmael as the son of the promise. Isaac, the son of Sarah was the one called the son of the promise from God.
Romans 9:9:
9For this is the word of promise, At this time will I come, and Sarah shall have a son.
Hebrews 11:17
By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,
Genesis 16
1Now Sarai Abram's wife bare him no children: and she had an handmaid, an Egyptian, whose name was Hagar.
2And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.
3And Sarai Abram's wife took Hagar her maid the Egyptian, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife.
4And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes.
5And Sarai said unto Abram, My wrong be upon thee: I have given my maid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: the LORD judge between me and thee.
6But Abram said unto Sarai, Behold, thy maid is in thine hand; do to her as it pleaseth thee. And when Sarai dealt hardly with her, she fled from her face.
7And the angel of the LORD found her by a fountain of water in the wilderness, by the fountain in the way to Shur.
8And he said, Hagar, Sarai's maid, whence camest thou? and whither wilt thou go? And she said, I flee from the face of my mistress Sarai.
9And the angel of the LORD said unto her, Return to thy mistress, and submit thyself under her hands.
10And the angel of the LORD said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.
11And the angel of the LORD said unto her, Behold, thou art with child and shalt bear a son, and shalt call his name Ishmael; because the LORD hath heard thy affliction.
12And he will be a wild man; his hand will be against every man, and every man's hand against him; and he shall dwell in the presence of all his brethren.
