لَهُ الْمَثَلُ الْأَعْلَىٰ (For Him is the highest attribute - Ar-Rum 30:27 ⧉ ) The word مَثَل mathal is used for any such thing which has resemblance and similarity with something else, but its being exactly like that is not necessary. Therefore, the Qur'an has used the word 'mathal' for Allah Ta’ ala at several places, as in this very verse, and in another but Allah Ta’ ala's Being is completely beyond resemblance. (That is why the word 'mathal' has been translated above as 'attribute', which is also a possible lexical meaning of the word.)
