The ruling on using the vocative particle "ya" with the names and attributes of Allah

Question:
And the thing upon which words are constructed is "ya," as in "O human, O Allah, O Messenger of Allah, O Messenger of Allah, O Merciful One of Allah." They said, they said, do not tire yourselves. No. Allah obtains what is in His people and it is easy for them except for a visit.

Answer:
Allah knows everything; there is no obstacle to His knowledge. He knows the ant and He knows the galaxy, meaning the stars in the sky. Allah knows everything, Glorified and Exalted is He, what is on the earth and what is in the sky. This is permissible. As for saying "O Glorified be Allah," "O Mercy of Allah," or "O such and such," this is not permissible. The vocative particle "ya" is not used; rather, one supplicates by saying, "O Allah, have mercy on me," "O Allah, provide for me."
You say "Subhan Allah" (Glory be to Allah) and "Alhamdulillah" (Praise be to Allah); you do not say "O Subhan Allah." You say "Subhan Allah." You say "Allahu Akbar" (Allah is the Greatest); you do not say "O Allahu Akbar." It is not permissible to add the "ya." This is an addition to the dhikr (remembrance of Allah), an addition to the dhikr. And if it is a vocative directed at an attribute, this is not permissible, because it is not permissible to address an attribute; rather, one addresses the One to whom it is connected, which is Allah, Glorified and Exalted is He.
