What is the ruling on what the poet Hisham Al-Jakh said in his poem "The Last of What Was Distorted in the Torah," describing Palestine as a harlot, and describing the Palestinian and Arab people as cuckolds, and calling for dissolution, and mocking religious rituals?

We have not read the poems of the mentioned poet, but based on the lines quoted, we see an overreach and inadequacy in expression. However, it cannot be definitively stated that the speaker intends to disparage Palestine or mock Islamic worship and rituals, as this would be an act of disbelief (kufr) that expels one from the fold of Islam. His intention might be to criticize the Arabs who caused the loss of Palestine by their inaction and preoccupation with superstitions instead of preparing for struggle and jihad. We say this because a definitive judgment that he mocked religious rituals would entail ruling him an infidel, and this is a serious matter.
