And if you say: He is not able to prevent his companion from his will? Then they are incapable from the perspective that you said they are capable.

If you say: That one of them is able to prevent his companion, and the other is not able.

Then the Capable is the Lord (Ar-Rabb), and the Incapable is the Subject (Al-Marbub).

And if you say: They reconciled upon the actions: one gives life, and the other causes death.

Then reconciliation and peacemaking do not occur except after difference and resistance; thus incapacity has entered upon them both together, since neither one of them is capable of all the actions. And whoever is incapable is not Pre-eternal (Qadim).

And likewise, it is binding upon you, if you believe that they are a group, what was binding upon you regarding the two in the argumentation. Thus, it is established and correct that He is One, as no division remains other than Him.

And Allah is the Guide to the Even Path.
