We the Palestinians are the descendants of the Israelites and not you.so if anything is given it is given to us.
The Quran is 500 page long not just few sentances that you can cherry pick from.
The Quran mentioned the story of the Israelites (who have no genetic link to modern Jews) and how they were opressed in egypt and god told them to go to the holy land because they were the true faith and followers of the prophet Moses.
But When Muhammad came now the muslims are the true faith and so his followers inherits the holy land and that is what the Quran and the disciplines of prophet Muhammad did when they captured Palestine and turned it Islamic.
The Quran also mentioned that in the end times the Jews will be gathered in Palestine and that they shall fight the muslims (god servants) and god shall grant muslims victory and the muslims shall retake the land and liberate Alaqsa mosque from them.
In short as per the Quran the land is granted to the righteous people who at one point were the followers of moses but when islam came it is now the muslims.
That is what the Quran say about the issue in complete and not cherry picking.
“And certainly We wrote in the Book after the reminder that (as for) the land, My righteous servants shall inherit it”
“So when the second promise came We raised our servants that they may bring you (jews) to grief and that they may enter the mosque as they entered it the first time”Quran 17:7
Yu dont need to adhere to the quran but you should not falsefy what it says.
