about letting the beard grow and trimming the mustache, and what is your guidance?

Question:
Shaykh Salih asks about letting the beard grow, trimming the mustache, and what is your guidance? May Allah reward you with good.

Answer:
This is among the characteristics of the fitrah (the innate natural disposition), and among what the Prophet (peace and blessings be upon him) commanded, which is letting the beard grow, meaning honoring it and letting it hang down, and not subjecting it to cutting or shaving, and likewise not subjecting it to dyeing with black, which the Messenger of Allah (peace and blessings be upon him) forbade. All of this is prescribed regarding the beard: honoring it, letting it hang down, and not subjecting it to cutting, shaving, or dyeing with black if there is any white in it; rather, it is dyed with a color other than black.
As for trimming the mustache, it means cutting and clipping it so that it is not left to grow long, but rather it is maintained by cutting or clipping, and it is not left to grow long and disfigure the face. For among the customs of the disbelievers, and of the Muslims who imitate them, is that they contradict the Sunnah of the Prophet (peace and blessings be upon him), and they contradict the fitrah (the innate natural disposition) upon which Allah created people, which is among the ways of the Prophets. They shave their beards and let their mustaches grow long and full. This is a contradiction of what Allah (Glorified and Exalted is He) has prescribed. The obligatory thing is the opposite: letting the beard grow and keeping it full, and trimming the mustache, because this is beauty, and this is perfection for men. As for the opposite, that is ugliness and disfiguring the appearance. The greatest of that is contradicting the Prophetic guidance, without which there is no rectification for the servant except by following it and holding fast to it. Yes. May Allah reward you with good, and may Allah reward you.
