There are five basic signs in mathematics.
- + (addition)
- – (subtraction)
- x (multiplication)
- / (division)
- = (equals)
And they apply to everything except for one case.
So, the question is:
Who is he to whom you can not add anything, or subtract anything, or multiply him, or divide him. None equals him?
The answer is: God.
And this is expressed in Sura 112 in the Quran:
Sura 112: Absoluteness (Al-Ikhlaas)
[112:0] In the name of God, Most Gracious, Most Merciful
[112:1] Proclaim, “He is the One and only God.
[112:2] “The Absolute God.
[112:3] “Never did He beget. Nor was He begotten.
[112:4] “None equals Him.”
