Hadith 5476
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Magians were mentioned in the presence of the Prophet (peace and blessings be upon him), so he said: They let their moustaches grow long and shave their beards, so you do the opposite of them. So Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to trim his moustache in such a way as the hair of a goat or a camel is trimmed.
