Is it permissible to say, "The Lawgiver, may Allah's prayers and peace be upon him," and what is the ruling on the one who says it, and is there any lawgiver other than the Prophet, may Allah's prayers and peace be upon him?

The word "al-Shari'" (the Lawgiver) is an active participle that Muslims use to refer to Allah, the Almighty, or to His Messenger, peace be upon him, because he is the one who clarifies what Allah has legislated. "Al-Shari'" is not considered one of Allah's Beautiful Names because Allah's names are divinely ordained (tawqifiyyah). If it is asked, "Is there a lawgiver other than the Prophet?" the common intention is that the Prophet is the only one who conveys the law from Allah. It is inconceivable for a Muslim to deny that Allah is the One who revealed the law.
