Asak,
This is a not a debatable point at all.. Beard has to be long like you said brother Shaheer. Imitating Jews and Christians is not allowed. Goatees etc are not allowed.
Beard according to DR Zakir Naik

There are various hadith that testify to this(BEARD) in Bukhari, Muslim, Tirmidhi and others. The Muslims are told to be different from the Mushrikeen by trimming the moustache and growing the beard; prophet Muhammad (saw) will turn his face away from the one without a beard on Yawmul Qiyammah; there's also another hadith in Bukhari that prohibits removing the hair on the sides of your face.
Is having Beard Fard or Sunnah???

Imaam Ahmad Bin Hanbal, Imaam Abu Hanifah and Ath-Thawri (Rahimahullah) said "All agreed that if the beard is removed, it is an act of mutilation. If someone was to remove an other mans beard by force he would have to pay the full "diyah" or blood money for this cruel act just as if he had removed an eye or a limb of the victum." This is based upon the Sahih Hadith from Imaam Bukhari "Rasulllah (Sallallaahu alayhi Wasallam) forbade robbing and taking propery by force and he forbade mutilation ." Imaam Ahmed Bin hanbal and Imaam Abu Hanifah agreed this includes a mans beard.(Sahih Bukhari)
“It is not for a believer, man or woman, when Allah and His Messenger have decreed a matter that they should have any option in their decision. And whoever disobeys Allah and His Messenger, he has indeed strayed into a plain error” al-Ahzaab 33:36
“He who obeys the Messenger has indeed obeyed Allah.” (An Nisaa 4:80)
