I think the differing opinions are cos the idea of adornment or beautification is so subjective, strictly speaking if u allow nose piercing u should allow others as well which is where the opinion thats says ‘yes’ runs into trouble. One person’s adornment is another’s mutilation and I’ve also heard some ppl say that nose piercings are allowed cos they’re cultural, seems a bit odd that desi piercings are ok as they’re part of that culture (which is generally a mishmash of Hinduism and Islam anyway) but piercings that are western or from some other culture aren’t..
