Not once, were Ishmael or Ishmaelites mentioned in Exodus, Leviticus, Numbers or Deuteronomy. Not even the Book of Joshua. Each time, the land of Canaan being mention as a covenant, it was always in connection with the descendants of Abraham-Isaac-and-Jacob, hence to the Israelites-Jews, not Abraham-Ishmael (hence not to the Ishmaelites), and not to the Edomites (Esau's descendants).
The land was not meant for every descendants of Abraham. That is what it say in the Torah or the OT Bible. Whether any of these biblical figures existed, is a different question. Whether God existed or not, is also another question. Whether the covenant about the promised land existed between God and the Israelite is...you guess it, another question.
Your OP was quite specific about the Jews and the (holy) land. You wanted sources, several of us had provided the sources, but you're still not satisfied.
Whether the modern Israeli-Jews or Palestinians deserved that land, is a whole different question, and I don't care to debate it. Quite frankly I sick of both sides, and as far as I am concern both sides are at fault, as well as the Arab neighbors (Syrians, Jordanians, Egyptians). It is bloody mess, and there is no perfect solution to it.
Like or not, what those scriptures say, you have simply ignored. No where in the Torah does it say Canaan belonged to the Ishmaelites, Arabs or Muslims, hence your question is answered.
