There is a scholarly consensus from the saheeh ahaadeeth that it is an obligation (fard) to trim the moustache and let the beard grow. The important thing is that Muslims distinguish themselves from the mushrikeen (historically speaking) or as we know today, kafirs.
I've got a thing about beards, especially the Noel Edmonds type (PBUH). It's a vanity thing. It implies that you've stood in front of a mirror carefully shaving up to the edges, and the implied statement is 'wow how cool do I look with this beard' whereas 'you look like a right naff toss-pot or a terrorist' is nearer the mark.
i remember that album coming out, i sild loads to the students at edge Hill on the first day, it was a big thing back then, an eager;y awaited Bowie album.
