Al-Quddus (IT)
Allah is free of any imperfection, he has no shortcomings, and evil are not attributed to Him. For all that is perfect and sublime attributes belong to Him.
From the root q-d-s which has the following classical Arabic connotations: to be pure, clean, spotless to be far removed from impurity or imperfection to be holy, sacred, hallowed.
He is Allah, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Bestower of Faith, the Overseer, the Exalted in Might, the Compeller, the Superior. Exalted is Allah above whatever they associate with Him. (Holy Quran 59:23)
Whatever is in the heavens and whatever is on the earth is exalting Allah, the Sovereign, the Pure, the Exalted in Might, the Wise. (Holy Quran 62:1)
