What is the interpretation of the phrases (All salutations are for Allah, all pure things are for Allah, all good things and prayers are for Allah) and (Peace be upon the Messenger of Allah) and (we remove for You and we remove) in prayer? And does the meaning of "Subhan Allah wa bihamdihi" differ from "Subhan Allah walhamdulillah"?

"Peace be upon you, O Prophet" has two meanings: The first is that "Peace" (As-Salam) is one of Allah's Beautiful Names, meaning that Allah protects you and is pleased with you. The second is a supplication for his well-being. As for "SubhanAllah" (Glory be to Allah) and "Alhamdulillah" (Praise be to Allah), they do not require explanation due to the clarity of their structure and meaning. Their meaning is one: the glorification and praise of Allah.
