What does the saying "Nothing is more harmful to creatures than the Creator" mean, and is it correct?

The statement, "There is nothing more harmful to creation than the Creator," is attributed to Abu Talib al-Makki, and he was declared an innovator (mubtadi') because of it. Some have tried to defend him, but the phrase is ugly even if it was intended to mean that Allah alone possesses the power to harm and benefit. This is because Allah does not decree harm out of malice, but rather out of justice and wisdom. Furthermore, people wrong themselves, and trials for believers are a mercy. Moreover, praise of Allah involves describing Him with the ability to both benefit and harm together, not just mentioning harm alone, because perfection lies in the conjunction of His Beautiful Names with each other. Therefore, this phrase should be avoided due to its lack of proper respect for Allah and its failure to magnify Him appropriately.
