The ash rubbing together is not why.... And no they didnt teach this in any school I went to, not even college geology or meteorology did they cover this for some reason.
What happens:
"Thankfully, the ash that comes out is hot enough so that not every particle is neutral: many are positively charged ions and many are negatively charged ions.
If you can make something push the positive ions differently than it pushes the negative ones, you can create a charge separation! If you get enough charges separated, you can make a large enough voltage to give you lightning!"
