I actually thought that part was perfectly clear.

> In general, the letter combination ال should be common.

So if your text has more than a few words, you should be able to look though your text and see that somewhere.

I can't read Arabic but I can recognize that pattern. I went to https://www.bbc.com/arabic and could find numerous occurrences.

It's a bit like saying "if you have a paragraph in 'English' and it has no e's in it, it's probably not English."
