وَلَا شَيْءَ مِثْلُهُ.
Nothing is like Him.
Clause structure: Lā shayʾa negates any thing without narrowing the subject to a single example. Mithluhu specifies that the negated relation is likeness.
Meaning and inference: No type or individual among created beings can be treated as a true equal of the divine essence.
Limit of inference: This general denial must not be turned into a denial of all divine attributes: resemblance is rejected, not the reality of attributes.
