Narrated Ibn `Umar: Allah's Apostle said, "To shave the pubic hair. to clip the nails and to cut the moustaches short, are characteristics of the Fitra."

Narrated Abu Huraira: I heard the Prophet saying. "Five practices are characteristics of the Fitra: circumcision, shaving the pubic hair, cutting the moustaches short, clipping the nails, and depilating the hair of the armpits."

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.
