As far as we know Abraham did not have siblings that we know of.
Abraham!
Abraham
Abraham was the christians father in faith and a person honored by the Muslims
because he believed in god and did what he asked
Judaism, Christianity, and Islam.
It says, God spoke to Abraham and commanded him to take his son to Mount Moriah and offer him as a sacrifice to God. This was God's test of Abraham's faith. Abraham loved his son very much, but did not hesitate to follow God's words for he was a man whose faith in God was strong. As Abraham and his son reached the place where the sacrifice was to be performed, Isaac said to his father, "Father, where is the lamb that is to be sacrificed?" Abraham replied, "My son, God will provide the lamb". Because, Abraham was honest to his God, his son was also honest to his father Abraham.
There is no specific mention of Abraham's siblings in the Bible. It primarily focuses on Abraham himself, his wife Sarah, and his son Isaac.
