Did Ibn Hajar, Al-Shawkani, Ibn Qudamah, and Al-Majd dislike Ibn Taymiyyah shaving the beard, and did Ibn Hajar permit trimming what is less than a handful without dislike?

If the questioner is referring to Ibn Hajar al-Haytami al-Shafi'i, it is reported from him in "Tuhfat al-Muhtaj" that he stated the dislike (karaha) of shaving the beard.

If the questioner is referring to Al-Hafiz Ibn Hajar Al-Asqalani Al-Shafi'i, no explicit statement from him on the dislike of shaving the beard has been found. However, he mentioned that Al-Ghazali disliked some characteristics related to the beard.

As for Al-Shawkani, no statement from him on the dislike of shaving the beard has been found. Perhaps he is referring to what he transmitted from Qadi Iyad regarding the dislike of shaving and trimming the beard.

No explicit statement from Ibn Qudamah on the dislike of shaving the beard has been found, except for what might be understood from his statement in "Al-Sharh Al-Kabir" regarding the dislike of taking what exceeds a fistful.

No statement from Al-Majd Ibn Taymiyyah on this matter has been found.

The issue of taking from the length and width of the beard is a matter of disagreement among scholars.

The majority of scholars, ancient and contemporary, hold the view that growing the beard is obligatory and shaving it is prohibited.

In summary: The opinion that shaving the beard is disliked (makruh) is a weak opinion, even if some scholars have stated it.
