1-When we say that Allah Almighty cannot do this thing, it is not a deficiency in him, but because this is not verifiable, because it is impossible, his will is not related to him in the first place, and it is like creating a partner, another creator, just like him, because he will be created, and this characteristic is not applicable to Allah Almighty.
2-When Shaykh al-Mutahari said that Allah Almighty bound himself by justice, he wants to deny his inability, without looking at the cause of wisdom, the subject of wisdom is taken for granted.
