And the third is distinguishing between the obligatory, the Most High, and the existence of the possible (the difference between the obligatory in existence, which is Allah, and the possible in existence, which is the created being)

The Shaykh :"And the third is distinguishing between the obligatory, the Most High, and the existence of the possible"
That is, they distinguish between the obligatory existent, which is Allah, and the possible existent, which is the created being. It is said: The Lord’s essence is His existence, unlike the created being. Thus, the statements are now three: either the negation that existence is the essence, or that it is the essence and composite, or that the distinction lies between the existence of the possible and the existence of the obligatory.
