Is it permissible to write or utter the words "the Legislator" (al-Musharri') and "the Just" (al-Adl) in the context of work, intending to refer to the drafter of the constitution and the authorized Islamic marriage officiant, knowing that the word "al-Musharri'" is used for Allah or His Messenger, and "al-Adl" is one of Allah's Beautiful Names? And would this result in falling into sin or an act that nullifies Islam?

There is no harm in naming the Shar'i Ma'dhun (Islamic marriage officiant) as "al-Adl" (the Just) because "al-Adl" is not one of Allah's names exclusive to Him, glory be to Him. Rather, it is one of the shared names that can be applied to Allah and to others, intending for creatures something different from what is intended for Allah Almighty. However, applying the name "al-Musharri'" (the Legislator) to anyone other than Allah Almighty is not permissible because absolute legislation belongs to Allah alone, and this word is not applied to a human being, neither linguistically nor technically.
