Even the Qur'an admits that the Land of Israel belongs to the Jews

It's true!

 I've checked in two different translations of that tendentious book.  The seventh Sura(h), also called 'Al Araf', in verse137 promises the land to the East and West of the River to Israel. The Surah is mostly a précis of Exodus with other bits. From the context, the river must be Jordan. This is also confirmed in Surah 5:21/23 depending on the translation. This much I have checked and verified for myself.

I understand that there are other Surahs on similar lines.

Israel Today has published an article on the subject.

The Koran promises the Land to the children of Israel because they suffered in Egypt, according to Nissim Dana, an Israeli expert on Islam who spoke with Israel Today reporter Olga Zenkova.

It is behind a subscription wall but I have read the article in the printed magazine. Some Muslims try to wriggle out of these verses but others are more open. Sadly, the article does not list all the verses.

Many Muslims are completely unaware of these verses as they do not read the Qur'an. They are told that translations are not accurate and that they need to learn Arabic. Even the Arab Muslims do not read the Qur'an.

All of which begs the question, "What are they fighting Israel for?" The answer is that they want to keep what they have conquered in the past and that they want the world for Islam.
