وَلَا شَيْءَ مِثْلُهُ.
Nothing is like Him.
Reading the terms: Mithl denotes a likeness or equal. The negation is not merely of physical shape; it denies any created counterpart to Allah in essence or attributes.
Boundary of meaning: Affirming divine attributes is compatible with denying resemblance to creatures. An affirmed attribute does not imply a human mode of possessing it.
Takeaway: Nothing is truly comparable to Allah.
