Is that a Hadith?
Here are some gems courtesy of Sahih Bukhari.
Volume 7, Book 72, Number 780:
Narrated Nafi':
Ibn Umar said, The Prophet said, 'Do the opposite of what the pagans do. Keep the beards and cut the moustaches short.' Whenever Ibn 'Umar performed the Hajj or 'Umra, he used to hold his beard with his hand and cut whatever moustaches. Ibn Umar used to cut his moustache so short that the whiteness of his skin (above the upper lip) was visible, and he used to cut (the hair) between his moustaches and his beard.
Volume 7, Book 72, Number 781:
Narrated Ibn 'Umar:
Allah's Apostle said, "Cut the moustaches short and leave the beard (as it is)."
Volume 9, Book 93, Number 651:
Narrated Abu Sa'id Al-Khudri:
The Prophet said, "There will emerge from the East some people who will recite the Qur'an but it will not exceed their throats and who will go out of (renounce) the religion (Islam) as an arrow passes through the game, and they will never come back to it unless the arrow, comes back to the middle of the bow (by itself) (i.e., impossible). The people asked, "What will their signs be?" He said, "Their sign will be the habit of shaving (of their beards). (Fateh Al-Bari, Page 322, Vol. 17th)
And some gems from Sahih Muslim:
Book 002, Number 0502:
'A'isha reported: The Messenger of Allah (may peace be npon him) said: Ten are the acts according to fitra: clipping the moustache, letting the beard grow, using the tooth-stick, snuffing water in the nose, cutting the nails, washing the finger joints, plucking the hair under the armpits, shaving the pubes and cleaning one's private parts with water. The narrator said: I have forgotten the tenth, but it may have been rinsing the mouth.
And those stupid orange beards you see around:
Book 030, Number 5780:
Ibn Sirin reported: I asked Anas b. Malik whether Allah's Messenger (may peace be upon him) dyed his hair. He said: He had not reached the stage when (he needed) dyeing (of his white hair). He had a few white hair in his beard. I said to him: Did Abu Bakr dye his hair? He said: Yes, with hina' (henna).
Oh what marvelous wisdom!
