Felix Siauw is a popular Indonesian author and speaker with over a million Twitter followers.
Earlier this month, he posted a 17-point Twitter manifesto about how selfies could be seen as a sin for Muslims.
"3. If we take a selfie, sift through and choose our best pose, and then we're awed and impressed by our selves – worryingly, that's called PRIDE" (this translation and all the following through Coconuts Jakarta).
"5. If we take a selfie and we feel cooler and better than others – we've fallen into the worst sin of all, ARROGANCE".
In one tweet, Siauw singled out women:
"9. These days many Muslim women take selfies without shame. There are usually nine frames in one photo with facial poses that are just – My Goodness – where's the purity in women?"
Now, as you may know, selfies are kind of a big deal in Indonesia.
Indonesia was actually the place where the selfie stick first began, according to Google.
Even the president is a fan.
So how did women respond? With #Selfie4Siauw, of course.
This isn't the first time selfies have fallen foul of Islamic religious leaders.
Last year, they expressed their anger after people were seen taking selfies on the hajj — the journey millions of Muslims make to Mecca in order to fulfil one of the five pillars of faith.
