Ghazali and Ibn al-Arabi asserted a related concept known as "wahdat al-Wujud" in Sufi literature. Often translated as "unity of Being" and confused with pantheism (which it is not), it could encompass what Aquinas said, "the sheer act of 'to be' itself", but with the additional restrictive clause that "nothing else 'is' itself". Which is a significantly more precise predicate than "God is a verb".
