The addressee here is the Prophet (saws), who is the most knowledgeable of this language. Meaning, this night is beyond human understanding. As if Allah (swt) saying to his Messenger: Unless we give you its meaning, you will not get it. Therefore, the word “Al-Qadr” includes a meaning above the verbal meaning; which is not reflected in the word itself, the evidence of this is Allah’s saying: (And what can make you know what is the Night of Decree?)
The general meaning in Arabic of “Laylat al-Qadr” is the night of greatness, honor, and high status.
