Well, this has been entertaining.
Many (30 or more) years ago I was on a transatlantic flight when suddenly three or four bearded and ringleted gentlemen stood up, unbuttoned their black frock coats, extracted one arm, buttoned the coats up again, rolled up the shirtsleeve on the aforementioned arm, and went through their prayer ritual.
It didn’t alarm me then but I suspect it might alarm me now, and certainly alarm some other passengers. Whether or not the original question was well expressed or well written, I think it was probably worth asking.
