Which is more linguistically and legally correct in the grammatical parsing of the word (Allah): "Lafẓ al-Jalalah" (the word of majesty) or "Ism al-Jalalah" (the name of majesty), and why?

The name "Allah" is a proper noun for the sacred Divine Essence. It is His most righteous and comprehensive name. The word denotes the meaning of divinity, i.e., that Allah is the possessor of divinity over His creation. Both expressions, "Lafz al-Jalalah" (the majestic word) and "Ism al-Jalalah" (the majestic name), are correct and used by scholars.
