Hi there,
The similarities between Arabic and Hebrew letters come from their shared Semitic roots—they evolved from similar ancient scripts, which is why some letters look and sound alike. That doesn’t make Arabic dangerous to use at all. It's a rich, complex, and beautiful language spoken by millions around the world.
It’s kind of like asking “how do you know your face shape” just because two face shapes look similar—it’s about understanding the context, not assuming one is problematic because it resembles another.
