Palistine Occupied Land Which Parts?

I'll admit I aint clued up on this issue can someone explain to me which parts are occupied is masjid al-aqsa in occupied land?

east jerusalem is occupied so palestinians say it is but whats crazy is the reason it is occupied is because corrupt arabs started a war with israels. but it is really long and boring and everyone will start fighting.

whats officially occupied land is the west bank, gaza, golan heights and east jerusalem...
but we all know that ALL of israel is occuppied territory because no matter when it happened or how it happened it is never any group of people's right to buy half the land then say we are the majority lets call this place israel and kick the people out or basically drive them out...
