What is the order/command/rule/law in regarding to keep beard in case of man?

It is Fa’rd to keep at least one handful beard for man. It is Haarwam and qaabirwah gwunah to cut or shave below this amount. French cutting, wahabi cutting, jaamati cutting, chinese cutting or any cutting to right, left or below chin to make design is Haarwam and Qaabirwah gwunah. It is suppose to mock with/make fun with beard. So keeping at least one handful beard is legislatively Fa’rd and ideally it is Sunnah. To do contrary/opposite to it is disobedience and the cause of gwunah.
