they don't have anything else to be strong outside of hope of religion

This doesnt seem right to me. Palestinian people resist and persist because they are colonized people wanting liberation, self determination and through their will to live. Just like the Koreans did, just like the Vietnamese did, just like the Haitians or Algerians did. Just like hundreds of millions did under as bad or worse colonial or imperial opression. Palestinian resistance is admirable but it isnt something historicaly unique that needs the "hope of religion" or the "importance of islam" in order to exist or be explained. At best those are of symbolic importance and manifesting due to the particular superstructure in Gaza but the actual struggle and anti-colonial martyrdom and bravery is something that has been replicated again and again across massively different religious and cultural contexts.

Palestinian people persist and would have persisted just as much in the absense of Islam. If they were cristian , atheist or buddhist. As tens if not hudred sof thousands of non Muslim palestinians do and did. The Quran no matter how beautifuly written doesnt actualy provide any insight for a marxist in the analysis of how and why Palestinians persist and reading the biography of the Prophet and some book by a white dude that converted to islam are anything but foundemental in understanding or interpreting the palestinian struggle and neither are they particularly usefull for building or expanding any other struggle, neo-colonial or otherwise

Palestinians have everything most other opressed and colonized people had in order to be strong. And they are strong and would be strong outside of the "hope of Islam" .
