In grad school I rarely practiced, drank, partied, and so on. As a muslim I understood the contradiction in this. Nonetheless, I was always attracted by religion. One day, I stopped by a stand which was selling Islamic books / doing da’wah and struck up a conversation with the vendor. I said I wasn’t a particularly good muslim, and it had been many years since I was. (Note, I had had facial hair since being a teen). His response? “You’re not going to shave your beard, are you?” I was gobsmacked by that. I chuckle at how limited his idea of Islam was, to the purely superficial.
