A male Muzzie never wears gold but silver.
This is in context with the whole idea of cross dressing being wrong, because gold was worn by mostly women over history. However there are some scholars that say it isn't completely forbidden if it's just a wedding ring or something but as jewelry yes.
The trousers of Muzzies are never reach the earth. They length is between the knee and the knuckle.
This was so the trousers didn't get dirty, and so when it came to prayer the clothes weren't muddied by any substances which cannot be prayed with such as urine, animal faceas etc.
It was also a sign of vanity and pride at the time for mean to wear long trousers......and so the prophet said that it should be avoided...however since this is invalid in todays world. You won't find a lot of muslims adherering to this because not only is it just sunnah but is not so important now, just traditional for some cultures.
Muzzies wear a beard, but shave the mustache
Rubbish. It is sunnah and tradition for muslims to have a beard because the Prophet did, but it doesn't mean anything since it doesn't affect their intentions in belief of Islam.
The prophet once did say to do the
opposite of what the idol pagan worshippers did by cutting their moustaches short and leaving their beards long....the idol worshippers did it the other way round...
This was to mark and identify the muslims from the non-muslims but nothing more then that.
Muzzies have to wear a sort of fez.
Not true. This is just the tradition and culture of certain countries.
A Muzzie is commanded to wear a shirt, which covers the upper arms
.
I assume you are referring to a man in which his considered private parts require him to cover himself from the navel to the knee, so this is untrue what you said.
