What is the ruling on growing a beard if it makes one's face appear frightening, and is it permissible to trim or shorten the beard, following the example of some scholars and imams?

The Sunnah (definition) (Prophetic tradition) provides evidence for the obligation of letting the beard grow and the prohibition of shaving or shortening it. Violating this is considered a transgression against authentic hadiths, while hadiths claiming that the Prophet took from his beard are invalid. A distinction must be made between legitimate beautification, which encourages cleanliness and good appearance, and imitation of disbelievers and wrongdoers.
