What is the ruling on disliking the letting of the beard grow and the shortening of the garment, whether for oneself or for others, without disliking the religious ruling itself? And does this fall under the ruling of disliking what Allah has revealed?

Disliking the beard and shortening of the garment, considering them a Prophetic Sunnah (definition) and a legal ruling, falls under disliking what Allah has revealed, which is disbelief (kufr). However, disliking them due to one's natural disposition while acknowledging the legal ruling is not disbelief. Scholars have explicitly stated the permissibility of wishing for the alteration of rulings or their non-legislation. The love of religion and its teachings is a sign of the perfection of faith, for a person's faith is not complete until their desires follow what the Messenger brought.
