Islam obviously has a integrated history with Arabic. Christians and Jews spoke Arabic long before Mohammed went to his cave.
Arabic is not hard to learn for a Hebrew speaker. Its like learning German for an English speaker.
“Islam obviously has a integrated history with Arabic.”
Which is the issue for the Haredi -— you (in paticular, children — somewhat differnet for adults) are not supposed to study other religions.
I recall a problem at a religious school I went to -— the state required all schools to have a world religion class with an approved curriculum -— I recall studying ancient Greek/Roman paganism/classics -— and the teachers collecting the books at the end of class -— with Greek/Roman paganism being chosen on the theory that no impressionable child would be swayed to become a pagan.
