Nickname in Arabic

This is a question for a modern novel with a Syrian-British character who works in a mostly-English-speaking environment. His name is Qasim (قاسم‎) and given that most nicknames are shortened versions of the full name, his colleagues call him Qas.

I know that قاس has various other meanings in Arabic, but I wasn't sure if it would be considered impolite to someone to use it as a nickname, especially when the people using it don't speak Arabic. Would it be normal for an Arabic name to be shortened like that? Or would it be considered rude?

I know this is a bit of a vague question, but I'd rather be safe than sorry.
