[Clint N. Suhks]

Abraham's descendants would have their own country

That's Issac's country, which one is Ishmael's?

[muawiyah]

Same one! However, an angel of God guided Hagar to the vicinity of Mecca, and there she uncovered the well called Zim Zim.

It provides water even until today.

Ismael, unfortunately (from the Moslem point of view) was displaced from his status as First Born by Isaac because his mother was only a servant and not a true wife as was Sarah.
