Just throwing a pertinent point out there for any Muslims considering taking up this or any other current trends/challenges; for Muslims; beards are encouraged while moustaches are discouraged; most Muslims, including myself, have not attained the level of piety and devotion to our religion where we would grow a full beard in accordance with the prophetic traditions; accordingly, let us at least think twice before we take up new innovative trends which involve actions which are expressly disliked and discouraged in Islam; if we can't do the right thing, let us then avoid the wrong thing too; i don't mean to be a killjoy or a bore and I'd never say this publicly in some other countries including my own; but alhamdlillah I'm in a Muslim country among my Muslim brothers and I don't need to be afraid or reluctant or embarrassed to present this thought to those who might benefit from it; may Allah guide us all and open our doors :-)
