In 1948, the international community gave the land to Israel, including Palestine.

To Muslims, Allah is basically God as well, because Jews and Muslims share most of their beliefs.

The Jewish people have further developed the land, and have always lived in Israel. They have lived there for the longest, too.

God promised the land to the Israelis, and there is no higher authority than God himself.

The land was given to the Israelis by God, and he promised the land to them. It doesn't matter if the Palatines have always lived there, but it does matter because there is no higher authority than God.
