Does the behavior of human beings imply that God becomes imperfect, given that God is perfect and everything originates from Him?

It must be understood that there is no contradiction between the actions of human beings originating from them and Allah Almighty's general creation of all things. The deeds and words of servants originate from them by their will and ability, and they are from Allah Almighty in the sense that He created them as subsisting in others and made them their action. Thus, actions are attributed to Allah as their Creator, and to the servant as subsisting in them.

The existence of defect in the actions of servants does not necessitate its existence in the attributes and actions of Allah. Allah Almighty created good and evil for great wisdoms. Evil occurs in His creations, not in His actions. Allah Almighty possesses the Beautiful Names, which entail goodness. Evil is not attributed to Him singularly; rather, it is mentioned within His creations, or included in generalities, or attributed to its cause.
