Shaving the beard

These days it's common to see that many shias don't keep a beard, in fact some of our very famous zakirs (speakers/lecturers) are also clean shaved. Is this allowed as per ahadith?

Mustadrak al wasail

الجعفريات اخبرنا عبد الله اخبرنا محمد حدثنى موسى حدثنا ابى عن ابيه عن جده جعفر بن محمد عن ابيه عن جده على بن الحسين عن ابيه عن علي بن ابى طالب (ع) قال قال رسول الله صلى الله عليه وآله حلق اللحية من المثلة  ومن مثل فعليه لعنة الله

(In) al Ja'fariat informed us 'Abdullah informed us Muhammad (said) Musa told me; told us my father from his father from his grandfather Ja'far b. Muhammad(as) from his(as) father from his(as) grandfather Ali b. al Hussain(as) from his father from Ali b. Abi Talib(as) said: "Said Rasool Allah(PBUH): Shaving the beard is from mutilation and who mutilates, invokes the la'nat(curse) of Allah(swt)."

 

Is it allowed to shave a part of the beard?

Wasail al shia

محمد بن إدريس في آخر (السرائر) نقلا من كتاب (الجامع) لاحمد بن محمد ابن أبي نصر البزنطي صاحب الرضا (عليه السلام) قال

وسألته عن الرجل هل يصلح له أن يأخذ من لحيته ؟ قال: أما من عارضيه فلا بأس، وأما من مقدمها فلا

Muhammad b. Idris in end (al Sarair) quoted from book (al Jam'e) of Ahmad b. Muhammad b. Abi Nudhr al Bazanti, companion of al Redha(as) said "And I asked about the man if it's correct for him to derive/take (shave) from the beard?" (Imam(as)) said: "As from sides(cheeks) no problem, and as from beginnings (front), then no."
