This addition did not appear earlier in 'Abd al-'Azīz’s words. Either someone appended it in some copies, or the intended meaning is: “This alone is my position, and I only said that this is what I have believed and committed myself to.” Alternatively, it may mean: “This alone is what I say and believe.”
It is more likely that this addition is not part of 'Abd al-'Azīz’s words, for it does not accord with the sound argument he presented in his debate. Nor had 'Abd al-'Azīz previously said this or anything indicating it.
This is unlike his statement:
“Action is simply an attribute of Allah; Allah has the power to act, and nothing prevents Him from doing so.”
This is a sound and correct statement, although he had not said it previously. Hence, he did not say, “I said that.” Rather, he said: “This is what must be said, and what I must commit myself to saying, because I have explained that a created thing can only come into existence through an act proceeding from Allah’s power. That act subsists in Allah; it is not a separate created thing.”
This is what he meant by saying, “It is an attribute.” He did not mean that a particular act is inseparable from the essence of Allah Most High, for he said:
“Allah has the power to act, and nothing prevents Him from doing so.”
Thus, 'Abd al-'Azīz achieved his purpose: to establish an act through which Allah brought created things into existence by His power. He thereby established the proof that something distinct from created things, proceeding from His power, subsists in Allah Most High. Al-Marīsī, for his part, acknowledged Allah’s power.
