It’s not total bullshit, whatsoever. I’ve known a good few Muslims, who would not use alcohol, as either a disinfectant, or topical liniment - due to their Wahhabi interpretation, of the Quran.
There’s a whole thread, from over a decade ago, on a Kung Fu forum, where a “revert” went into depth, about why he could not purchase, or create a bruise liniment, from ethanol, because he claimed it went against the Quran. This despite the fact, the end product would be highly poisonous, and thereby de facto denatured…
I’ve also trained with people, who would only use liniments made from vinegar, as the base, for similar reasons.
So yes - some Muslims, will not use any alcohol products, whatsoever, for any reason!
