Is it correct to say: "I worship the attributes of Allah" or "I worship the Hand of Allah"?

Worshiping an attribute among Allah's attributes, or supplicating to it, is polytheism (shirk); because an attribute is not the one described (al-mawsuf), even if it is a description of Him. It is distinct from Him and independent. Thus, it cannot be worshiped. If a person were to worship an attribute among Allah's attributes, they would not be worshiping Allah, but rather that attribute. Allah, the Exalted and Glorified, is described by all of His attributes, so if you worship an attribute among His attributes, you have not worshiped Allah.
