(may Allah bless him and grant him peace):
“Abraham told only three lies, all of them for Allah’s sake.”
And Khubayb’s words:
“This is for God’s sake; and if He wills,
He will bless the limbs of a body torn apart.”
In these and similar expressions, the meaning is “in Allah’s cause,” that is, “for Allah Most High.” This is why Ibn Burhān and others objected to the theologians’ use of the expression dhāt Allah (“the essence of Allah”).
Since this is so, you have applied the word dhāt (essence) in a way the Arabs did not, without authorization from revelation. If someone were to say to you, “Allah is not an essence,” you would dispute his statement. Your opponent says the same regarding the terms “substance” and “body,” if he agrees with you on their meanings.
Furthermore, in the terminology of all of you, the terms “substance” and “body” have acquired a broader meaning than they had in Arab usage, for the Arabs do not call everything that occupies space
