And that thought of yours which you thought about your Lord, has brought you to destruction, and you have become (this Day) of those utterly lost!
(Quran, 41:23)
The people of hellfire will be brought before the fire of jahannam, and their ears, eyes, and skins will testify against them. They will ask their skins: why did you testify against us?
Their skins will reply: The one who grants everything the ability to speak, granted us the ability to speak. He is the one who created you initially when you were in the world, and to Him you will return in the Hereafter to give account and be requited. And you have not been hiding against yourselves, lest your ears, and your eyes, and your skins testify against you, but you thought that Allah knew not much of what you were doing. And that thought of yours which you thought about your Lord, has brought you to destruction, and you have become (this Day) of those utterly lost!
The people of jahannam were destroyed by their lack of knowledge and belief in Allah being As-Samee’. Ignorance of one Name led them to their doom.
It would then be understood that to be victorious, one should know every Name and Attribute of His Lord, and believe it with full certainty by applying it in every aspect of his life.
We should not believe in one Name more than we do the other, because they all belong to Him. We should believe that Al Mujib answers when He is asked, just as we believe that As Samee’ hears when we call upon Him.
This is what saves us from destruction.
