Analysis of information sources in references of the Wikipedia article "Shenandoah (beard)" in English language version.
"Cut the moustaches short and leave the beard," says the famed hadith found in a collection by Muslim scholar Muhammad al-Bukhari. Muslim men who grow out their beard and shave their lips are emulating the Prophet Muhammad's actions, say the religiously inspired fans of the style. And while many particularly defined groups, such as some Salafists and Wahhabists, adhere to the teaching, the existence of clean-shaven Muslim men – and those bald-chin moustache-wearers such as Afridi – prove that such teachings, like the wearing of the hijab, are not accepted universally.
However Salafists - the ultraconservative fundamentalist Muslims - like to let their beards grow long and wild, often leaving their upper lip clean-shaven as a nod to how the Prophet Mohammed wore his own beard 1,400 years ago.
