What is the ruling on trimming the beard to the width of a fist?

The questioner:
He says: I trim my beard, but I do not shave it, and I trim it to the width of a fist. My father said to me, "Do not look at me until you let your beard grow."

The Shaykh:
Yes. To the width of a fist. My father said to me, "Do not look at me until you let your beard grow." Yes.

The questioner:
He allowed me to greet him with the sunnah greeting from a distance. What do you advise me to do, Your Eminence the Shaykh, and what is the correct position regarding the beard?

The Shaykh:
What is the correct, the true, the true position regarding the beard is that it should be left to grow and left alone, and one should not touch it, neither by cutting, nor trimming, nor shaving, nor anything else, but rather it should be left to grow. The Messenger (peace and blessings be upon him) said:
"Honor the beards, let the beards grow, and grow the beards." All of these are commands from the Messenger (peace and blessings be upon him). So your father is right in this, he is right in this, that you should leave your beard as beauty for you and adornment for you. It is one of your limbs. How do you oppose it?
How do you oppose it? Except that Satan makes this attractive to you, and bad company and blind imitation are what led you to this. So you must repent to Allah, return to your right path, and accept your father's advice.
