With all due respect, somebody in Singapore does not know what they are talking about. All this stuff is Hindu, not Muslim.
There’s no such animal as a Muslim “Fakir”.
From Wiki: A fakir or faqir (Arabic: فقیر (noun of faqr); English pronunciation: /fəˈkɪər/) Derived from faqr (Arabic: فقر, "poverty") is a Muslim Sufi ascetic in Middle East and South Asia. The Faqirs were wandering Dervishes teaching Islam and living on alms.
Now, whether this guy really is a mystic or just a crazy asshole, is up for question. But fakirs are most certainly Muslim, not Hindu.
