عن ابن عمر رضي الله عنهما عن النبي صلى الله عليه وسلم قال:
«أحْفُوا الشَّوَارِبَ وأَعْفُوا اللِّحَى».
[صحيح] - [متفق عليه] - [صحيح مسلم: 259]

Ibn ‘Umar (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said:
"Trim the mustaches and let the beards grow."
Sahih/Authentic. - [Al-Bukhari and Muslim. This is the wording of Muslim]
The Prophet (may Allah's peace and blessings be upon him) enjoins that the mustache should be trimmed and not be left to grow; rather, it should be cut, and this should be done to a great extent.
On the other hand, he enjoins that the beard should be left to grow long.
