This Is My Faith - Al-fatlawi, Ali - الصفحة ٦٣ - More on Qualities of the Glorious Allah
we have just talked about and we excluded the Almighty Allah from them. But the proved qualities are again divided into two parts:
Essence qualities: we can know these qualities from observing the very essence of God. This way we find out that we cannot gather up the essence quality with its opposite. For instance, we cannot say He is the Omniscient and not the Omniscient; it is just impossible. He is Omniscient, the Omnipotent, the Superior, the Alive, the One, The Everlasting, etc. and His essence is always described with them i.e. these qualities can never be detached from Him.
Deed qualities: they are subject to the situation; one quality can be true in one condition but the opposite in another condition like the Creator, the Provider, the Merciful, etc. and so, Allah, Praised Be His Name, is Merciful to believers but He is not Merciful with polytheists.
Anwar: I see you are looking at your watch. Are we done for today?
Hasan: Yes, I think we’ll have to continue our discussion next time, Inshallah.
