What do you think the prophet Muhammed would mandate or prohibit for his followers if he were alive today?

I mean, in addition to all the stuff that's already in the Quran and Hadith. That's sort of a given, right?

I found myself watching a video on beards in Islam, and it struck me that the Hadith the video quoted all seemed to be about differentiating yourself from people who are not Muslim. Apparently wearing a moustache and no beard was common at the time, so for Muslims, it was everything but the moustache.

Do you think there are similar "do the opposite of everyone else" rules Muhammed would stipulate if he lived among us today? What would they be?

Or.. feel free to tell me if you think it would be wrong to put words in his mouth, too. Totally a reasonable position, all things considered. I wouldn't like it if I were him, come to think of it.
