[neerewed]

Brother please read the words of Allah.

"Ye have indeed in the Messenger of Allah an excellent exempler for him who hopes in Allah and the Final Day, and who remembers Allah." (Quran 33:21)

"What Allah has bestowed on His Messenger (and taken away) from the people of the townships,- belongs to Allah,- to His Messenger and to kindred and orphans, the needy and the wayfarer; in order that it may not (merely) make a circuit between the wealthy among you. So take what the Messenger gives you, and refrain from what he prohibits you. And fear Allah: for Allah is strict in Punishment." (Quran 59:7)

"And when the true believers are called to Allah and His Rasul (Sallallahu Alayhi Wasallam) [to accept and practice the law and commands of Allah and His Rasul (Sallallahu Alayhi Wasallam)] that he may pass judgement upon them, their ONLY reply is 'We hear and obey.' Such men shall surely prosper." (24:51)

Rasulullah (Sallallahu Alayhi Wasallam) said: "Anyone who shaves has no claim to the mercy of Allah"
- Reported by Ibn Abbas (R.A.) in Tibrabi

We must listen to our beloved Rasulullah (Sallallahu Alayhi Wasallam). It is command of almighty Allah.

I do not know which scholar you are referring to but look at what the 4 great imams of Jurisprudence have to say.

Hanafi

Imam Muhammed (R.A.) writes in his book "Kitabul Aathaar" where he relates from Imam Abu Hanifa (R.A.) who relates from Hadhrat Haytham (R.A.) who relates from Ibn Umar (R.A.) that he (Ibn Umar) used to hold his beard in his hand and cut off which was longer. Imam Muhammed (R.A.) says that this is what we follow and this was the decision of Imam Abu Hanifa. Therefore, according to Hanafies, to shorten the beard less than a FIST LENGTH is HARAAM and on this is IJMA (concensus of opinion).

Shafi'i

Imam Shafi (R.A.) in his Kitabul Umm states, "To shave the beard is HARAAM." (Shari Minhaj dar Shara Fasl Aqueeqa).

Maaliki

Shekh Ahmad Nafarawi Maliki in the commentary of Imam Abu Zayed's booklet states, "to shave the beard is without doubt haraam according to all Imams." It is also mention in "Tamheed" which is a commentary of "Muatta" (Sunnan Imam Malik (R.A.)) that to shave the beard is HARAAM and among males the only ones to resort to this practice (of shaving) are the HERMAPHRODITES (persons who possess both male and female features and characteristics).

Hanbali

The Hanbalies in the famous Al-Khanie'a Hanbali Fatawa Kitab state that "to grow the beard is essential and to shave it is HARAAM." Also in the Hanbali Mathab books "Sharahul Muntahaa" and "Sharr Manzoomatul Aadaab", it is stated "The most accepted view is that it is HARAAM (prohibited to shave the beard)."

Also note, according to scholars of Islam: "To shave off the beard is unlawful (haraam) and one who shaves his beard is legally speaking an unrighteous fellow (FASIQ); hence, it is NOT PERMISSIBLE to appoint such a man as an Imam. To say Taraweeh behind such an Imam is MAKRUH-E-TAHRIMI (near prohibition)" (Shami Vol.1, p.523)

The Durre-Mukhtar states: "No one has called it permissible to trim it (the beard) less than FIST-LENGTH as is being done by some westernized Muslims and hermaphrodites." (Vol. 2, p. 155). Also, "It is forbidden (haraam) for a man to cut off another's beard." (Vol. 5, p. 359).
