Is it permissible to say "O Wisdom of Allah" or "O Wisdom of my Lord," as the Imam of the mosque allowed?

Saying "Ya Hikmat Allah (O Wisdom of Allah)" is permissible if the intention is to express wonder at Allah's wisdom. However, if the intention is to directly supplicate the attribute (invoking the bare attribute), then it is forbidden and may even reach the level of disbelief and polytheism. This is because an attribute is not worshipped or invoked by itself as an independent deity; rather, Allah alone is worshipped with all His attributes. Scholars have agreed that invoking an attribute (as if it were independent) is disbelief because it makes the attribute independent of Allah, bringing good and repelling evil.

As for seeking refuge in Allah's attributes, such as "A'udhu bi Ridhaaka min Sakhatik (I seek refuge in Your pleasure from Your wrath)" or "A'udhu bi Kalimatillahit-Tammaat (I seek refuge in the perfect words of Allah)," this is not considered invoking the attribute. Rather, it falls under the category of seeking intercession with Allah through His attributes, which is legislated.

Regarding the common people's saying "Ya Rahmat Allah (O Mercy of Allah)," their intention is usually to seek Allah's help for His mercy to encompass them, not to invoke mercy itself. This is permissible, but they should be taught the correct phrases that leave no room for ambiguity, such as saying: "Ya Arhamar-Rahimeen (O Most Merciful of the merciful)."
