These passages come from the Koran:
Surah V:20 And (remember) when Moses said unto his people: O my people! Remember Allah’s favoour unto you, how he placed among you Prophets, and He made you kings, and gave you that (which) He gave not to any (other) creatures. O my people! Go into the holy land which Allah hath ordained for you. Turn not in flight, for surely ye turn back as losers.
Surah XVII:104 And we said unto the Children of Israel after him: Dwell in the land, but when the promise of the Hereafter cometh to pass, we shall bring you as a crowd gathered out of various nations.

Regardless of who owned the land in the past, the Israelis have proven to be superior to the Arabs. Just compare Israel with Arab countries.
